I'm getting the below error which I think is form the formula in the formula tool, pls advice.
Solved! Go to Solution.
What is your loop expression (it's not in the screenshot)? Everything else looks okay from what I see.
Oh - also check that there are no null values for Start Date. That could throw it off as well (depending on your loop expression).
@chiragpatel_1
Same with @mbarone , I believe there is some wrong with the loop expression formula in your Generate Row Tool.
It should like look some thing as below.
