I have a table were I utilize "last modified time" to be inputed based on the Specific field ("Checkbox").This sequence works well for what I am doing, which is; creating time logs for when we "Start" and "Stop" work on a specific task. I then have a formula set up "Datetime_Diff" where it grabs the difference between the two in minutes (set up as integer) so that I can log billable hrs towards a project (Time on Task).
Here is my problem... I have another table "billing" that I want to utilize a "rollup" field for, to grab the SUM of that data in my "Time on Task" field and have it contribute to a specific job number. I am utilizing this exact same method for and "expense" field but the field the rollup is connected too on that method is a "currency" field (which I cannot use on my time tacking).
I am sure there is a solution but I am not an expert.. yet!
