Calculating Totals on a Sub forms
I have designed an invoice which includes a datasheet sub form with 2 colums
to sum with a GRAND SUM on the main form. To avoid displaying £0.00 in every row I re-set the default value in the underlying table from 0 to blank Now I notice that the TOTAL VALUE BOX on the main form will not display a total if one of the column does not have an entry. I have to type a 0.00 value on at least one row to get it to function. Anyone know of a fix or work-around? Thanks

Use the Nz function
Nz([SomeField],0) + Nz([SomeOtherField],0) -- _________ Sean Bailey "Brian" wrote: I have designed an invoice which includes a datasheet sub form with 2 colums to sum with a GRAND SUM on the main form.
