Your wording here is a little confusing. Just FYI when asking questions, easier to say fields not columns, records not rows.  Then you say you're using a totals groupby query? That would work with across several records (rows) not fields (columns).

So if your adding togethor a total number like money costs in different fields for ONE record, you can just use a calculated field in a query. FieldA + FieldB Calculated Fields

If you're trying to get a count of which fields in ONE record have a value vs which dont, you can use an IIF Statement to show if it has data or null, then DCOUNT that IIF statement.

If you're trying to add numbers going down a field across multiple records, same link I shared above should cover that with a footer calculation.

Adam,
Thanks for your quick response.  Sorry about the wording, I'm coming from the Excel world.  Yes, I want to count each field (that has a value) in a record and show that count in a "totals" field.  I am using a query as I need information from two different tables. You are suggesting that I use an IIF statement and then DCOUNT?  Isn't there an easier way to do this? If not, can you direct me to the video that explains how to use these functions?  Thanks!

Yea I figured excel world :) no problem.  So just to verify, are you trying to get a count of fields that have a value? Field A has 5 in it, field B is null, and field C has 2 in it, so the COUNT would be 2, a count of fields that are being used and not null. Or are you looking for a SUM, FieldA + FieldB + FieldC so the answer you're looking for is 7?
