I am not sure of how to use expression in sharepoint designers. I have a variable called date, but its type string. I am attaching the workflow when an event is created. I need to SET the variable date to the START DATE of the event.
But I need a particular format YYYYMMDD
Something like this maybe:
=YEAR(Current Item:StartTime) + MONTH(Current Item:StartTime) + DAY(Current Item:Start Time)
