I have a time log form that has a date field I do not want to have to fill out every time as 90% of the time the date would be today's date. (Sometimes you will be entering something from another day and need to change it).
When an entry is added column A is always going to have something, so it should check to see if A is empty and if that same rows D is empty it will input today's date into D.
Some of the example's I have looked at were for onEdit of cell change it, but I could not get it to work with a form submit or even just have it automatically check all the cells in D and if empty put today's date (Only when B has value).
I have a function to sort the sheet right now that is called when on form submit/onEdit happens and would like to stick the new formula in the bottom of the same one (unless that is bad practice). The reason for this is less functions to have to add to the trigger list.
A: Timestamp | B: What | C: Paid? | D: Date
