Force calculation of a field during a script
I'm looking for a way (script function) to force a field to recalculate.
I have a field called START, that is a pop-up menu with values such as D1, D2, D3 and so on (Day 1, Day 2, etc.)
The field START DATE is a date field that calculates based on the D1, D2, etc... For example, if I enter D1, that field is able to tell me it's equal to January 15, 2013.
What I need is a way to insert a script step that will recalculate this START DATE field when a script is activated.
Is this possible?
