Need a formula to auto sum

[cwitt11]

Hello, I was wondering if what I want to do is even possible? I have a form that calculates a Total Profit on each separate document. I would like to have a calculated field in the form that would keep a running total of all the Total Profit from each entry and display it in a text box. Does anyone know a formula I can use in this calculated field? Thanks, Carol

This is difficult to do in query and form. https://support.microsoft.com/en-us/kb/290136

Textbox on report has a RunningSum property so it is quite simple on a report.

Thank you, I will try that.
