Auto-Calculation with null fields

[Evan McCutchen]

I have an Invoices form that has three rows of information, each with a
"quantity" and a "priceperunit" field. Also, each row has a "total" field
that auto calculates the total price of each line. Normally, we only use one
or two rows filled, and all third row fields are Null.

I have a field at the bottom of the form that is called "overallprice" whose
control source is set to "=[Total1]+[Total2]+[Total3]". If all three rows of
data have a "total" figured, then "overallprice" will autocalculate. If any
of the "total" fields are empty, then it will not work. Does anyone have a
solution so that I can have one of the "total" fields empty and still have
the "overallprice" field still calculate?

Thanks!

you may try this way
=nz([total1])+nz([total2])+nz([total3]
