I need to do the following on a query. I have a field we'll call Cost1 that I divide by .77 divide by field PackSize. I have another field called ReqPrice. I want to take the result of the first formula and subtract it from ReqPrice. If there is a difference, in other words, it doesn't equal 0 I want to output what number would need to be added/subtracted to the first formula so my 2nd formula equals 0. I hope that makes sense. Thanks!
