Hello,

I currently have a form with two subforms that tracks time and expenses.  In the time subforms, I have a calculated field for Time Worked and in the Expense subform, I have a calculated field for mileage.  I want to sum both subforms on the main form (tab) so the employee can see a total for their hours worked and total expenses.  I have tried numerous expressions, etc to get the totals but none successful.  Could you take a look at the attached sample database and advise what I need to do to get the totals to display as opposed to the "#Error or #Name.  My last expressions are included.

Any help would be appreciated

You can not sum with other unbound field

you should use in txtTotalRegHrs =Sum(IIf([TimeOut]>[Timein],[TimeOut]-[Timein],([TimeOut]+1)-[Timein])*24)

and by [Total Expenses] =Sum([ExpenseAmount]+([Mileage]*0.45))

Yep - Thank you.  Once I deleted the Textbox, it gave me the desired result.
