Here is my scenario: I have a project that has details stored in table1. These details are entered using form1. Some of these details are the amount of time spent on the project and the project number. I have several employees who will enter the project number into form2 as well as the amount of time spent on the project. These details are stored in table2. I want the calculated time results to appear in form1. The calculation will add all of the time spent on the project by any employees who worked on it. There are 20 employees. One may work on the project or 20 may. I have no way to determine who or how many will work on the project. The only thing that will tie it together is the project number. Can anyone out there help?
