I have three tables, one is a timesheet, one is quotes and the other is job cost.
The timesheet layout has a value list that allows you to select quotes from the quotes table, you can then assign a cost code, and then attribute hours per day, which are subtotalled .Each of these feilds are reptitions.
I want to be able to go to the job cost layout select a quote , get a summary of all the hours per cost code per quote accroos all time sheets.
i am stuck in the abyss and cannot find the door, can some one please turn on the light.
What you are describing is called a summary report with sub-summary layout parts. You define a summary field, place it in your sub-summary part, sort your records and you get the sub totals you want.
