1. Contextual |
6. Logic | 11. Choices |
| 2. System Values | 7. Data Conversion | 12. Data Interchange |
| 3. Math | 8. Data Sources | 13. Location |
| 4. Text | 9. Lists/Sets Of Values | 14. Process Steps |
| 5. Date/Time | 10. Repeats/Tables | 15. Advanced Maths |
| USEREMAIL() | User's Email Address |
| USERFIRSTNAME() | User's First Name |
| USERLASTNAME() | User's Last Name |
| USEREXTERNALID() | User's External Id |
| USERINGROUP() | Returns True/False if the signed-in user's group name or external ID matches the given name/external ID. USERINGROUP('group name or external Id') |
| ORGNAME() | Organisation Name |
| GLOBALVAL('keyname') Global Value |
Gets the Global Value for the specified key name (if any) |
| ORGMETA('key') Organisation Meta Value |
Gets the Provider Meta Data Value for the specified key (if any). For example if your Organisation setup contains a Meta Data key of billing_id then you may access this value across the platform with ORGMETA('billing_id'). |
| USERMETA('key') User Meta Value |
Gets the User Meta Data Value for the specified key (if any). For example if your User setup contains a Meta Data key of billing_id then you may access this value across the platform with USERMETA('billing_id'). |
| DEVICENAME() | The device name. |
| DEVICEOS() | The device operating system. |
| DEVICEOSVERSION() | The device operating system version. |
| APPVERSION() | The current version of the app installed on the user's device. |
| SCREENVERSION() | The version number of the current screen on the device. |
| SCREENDATE() Screen Last Updated (UTC) |
The date & time on which the current screen on the device was last updated for GMT (UTC) time zone. |
| VAL('dataname') Direct Value |
The VAL formula is intended for use when a dynamic dependency would lead to circular reference issues and is not dynamic when used alone, returning the value of the field referenced, 'dataname'. Example: IF(ISBLANK({{oneField}}), VAL('otherField'), {{oneField}}). This formula will evaluate once when the form loads and thereafter will only ever re-evaluate when the value of 'oneField' changes. This formula is not dynamically dependent on 'otherField' in any way since it does not contain a dynamic reference {{otherField}}. When the value of 'otherField' changes, this formula will not re-evaluate. |
| COUNTER() Screen Parameter |
Simple counter that increments by 1 every time a new Form entry is created in the app. Will left pad the counter with zero’s to the specified pad width length. Concatenate counter() with user data to generate unique numbers. NOTE: Counter numbers are device-specific. |
| TASK('key') Linked Task Data - APP ONLY |
Gets data value for the given key when this Screen is linked to a Task. Returns blank value if no Task is linked. The following Task keys are available: ADDITIONALINFO, COMPLETEATLAT, COMPLETEATLON, EXTERNALID, ID, ISOVERDUE, NAME, PERFORMWITHIN, COMPLETEBY, COMPLETEBYUTC, STARTTIME, STARTTIMEUTC e.g. TASK('NAME') returns the linked Task's name value. |
| TODAY() Current Date |
The current local date reported by the device. NOTE: Device dates can be inaccurate if the local time is not correct. |
| NOW() Current Date and Time |
The current local date and time reported by the device. NOTE: Device times can be inaccurate if the local time is not correct. |
| UTCTODAY() Current UTC (GMT) Date |
The current Greenwich Mean Time (GMT) date reported by the device. |
| UTCNOW() Current UTC (GMT) Date & Time |
The current Greenwich Mean Time (GMT) date and time reported by the device. |
| TASK-FIRSTAVAILABLE() |
Returns the 'First Available' automatic user assignment identifier. Useful for creating new Tasks that are randomly assigned to the first available user. Also handy to use as a Process Step field's 'Send Form To' value. The optional parameter allows you to restrict the Task assignment to only users within the given User Group name or external ID.
Examples of use: TASK-FIRSTAVAILABLE() will assign randomly to first of all available users TASK-FIRSTAVAILABLE('mygroup') will assign randomly to first available user in User Group named 'mygroup' TASK-FIRSTAVAILABLE({{myfield}}) will assign randomly to first available user in User Group name/ID matching the answer of field with name 'myfield'
|
| TASK-FIRSTTOCLAIM() |
Returns the 'First To Claim' user assignment identifier. Useful for creating new Tasks to be performed by the first user to claim. Also handy to use as a Process Step field's 'Send Form To' value. The optional parameter allows you to restrict the Task visibility to only users within the given User Group name or external ID.
Examples of use: TASK-FIRSTTOCLAIM() Task will be visible to all users TASK-FIRSTTOCLAIM('mygroup') will be visible to users in User Group named 'mygroup' TASK-FIRSTTOCLAIM({{myfield}}) will be visible to users in User Group name/ID matching the answer value of field with name 'myfield'

| STARTSWITH(val, startswith) Starts With |
Returns true or false result depending on if the given starts with text appears at the beginning of the given text value. Matching is case insensitive. e.g. if myfield has value 'ABCDEF', then: STARTSWITH({{myfield}}, 'ABC') result is true |
| CONTAINS(val, contains) Contains Text |
