I am attempting to calculate a date in my workflow based off the results of a calculated column in my list. I have a script that takes the choice from my "Duration of Project" field (15, 30, 60, or 90 days) and then creates a date that reflects each duration. I use "Calculate Date" set the value to "Expiration Date" and subtracted 10 days. I set this to a variable, varReminderDate.
My end goal is to send a reminder email 10 days prior to that expiration date. However, the calculate date action fails. I receive this error:
Is it even possible to do what I am attempting? I have tried this as a site workflow but my log shows the dates return as 1/1/000112:00:00 AM and 1/1/1900 12:00 AM. It then pauses until 1/1/0001 and sends.
