Adding two subtotals together.

I have a Subform with multiple columns in it. One column is calculated and
is subtotaled in the Form Footer. Another column is used to log any extra
hours worked by a volunteer that day. It too is being subtotaled in the Form
Footer.

Here are the two subtotals:

=Sum((DateDiff("n",[Start Time],[End Time])/60)*[Number of People])

=Sum([Other Hours])

I want to add these two subtotals together in a control box on the main form
so I can see at a glance the total number of hours volunteered by each
individual volunteer.


This is one of my failed attempts which results in “The expression you
entered contains invalid syntax.�:

=(([Volunteer Hours Subform]!Subtotal)+Nz([Extra Hours]))+(([Volunteer Hours
Subform]!Subtotal Other Hours)+Nz([Extra Hours]))

Any ideas? Thanks!

What is: [Extra Hours] where did it come from?

Try:

=(([Forms]![YourMainFormName]![Volunteer Hours
Subform].Form!Subtotal)+Nz([Extra
Hours]))+(([Forms]![YourMainFormName]![Volunteer Hours
Subform].Form!Subtotal Other Hours)+Nz([Extra Hours]))

I left [Extra Hours] in, but you may not get an accurate total.

Thanks Arvin! Your comment about [Extra Hours] made me realize that I could
completely get rid of that function. It will be redundant now and in the
process it lets me get rid of a really annoying rogue field in an unrelated
table.

It works! I had to slightly modify yours by adding [ ] around the Subtotals
& Nz() around each section and it works like a charm. Here’s my final.
Thanks!

=Nz((Forms![Active Volunteer Frm]![Volunteer Hours
Subform].Form!Subtotal))+Nz((Forms![Active Volunteer Frm]![Volunteer Hours
Subform].Form![Subtotal Other Hours]))
