I still continue to have problems. Let me see if I can explain and maybe you can give me possibly a better way to go.
I have a report that has as a footer. All, PC's, Notebooks, blackberry, cell phone, copier, router, (these are just summing the amount of records of a particular type)(the code is for software is =Sum(Abs([Type]="Software"))etc. When I print the "All" all pc's return a correct count, blackberry returns a correct count, etc. everything is fine. There are NO routers, so the txtRouters box displays 0, which is correct.
However, when I select Router as a report, I make all other (PC's, Notebooks, blackberry, cell phone, etc. invisible, so that they aren't seen). This works fine. But, there is no "type" router in the actual table, and instead of seeing a 0, I get the infamous #error.
Any help again will be greatly appreciated. I have worked on this for days and still have not come up with a solution.
