Dear Dev Talk:
I have a list that has multiple 'data' data columns and I want to calculate the days between the 'data' columns without requiring a user to modify each individual list item. I first thought of and created a site workflow, but I keep getting an error message. I think I am getting an error message because you cannot store more than one value in variable??? Since multiple items have the same status that is used to trigger the math operation, I think that is where I am getting my error.... Any help on how you can accomplish calculating multiple items using the same WF without requiring a user to modify each item would be much appreciated! Thanks!
