GLOBALVAL('keyname')
Say you have a common field in several Form Screens that the user has to select every time - e.g. a project, client or job number.
If the user tends to select the same value every time, then you should consider storing this in a Global Value.
Saving Entry Values For Reuse / Defaulting (Global Values)
Global Values are stored as text, so if you use GLOBALVAL() as an assignment to a Date/Time or Number field, then you will need to convert the value to the correct datatype of the target field. This is done using our TODATE() and TONUMBER() functions respectively.
