Customized Sales Reports

I have customized (with the help of a Navision expert) several reports. Now being on my own, I have ran into a problem. Within the Analysis Line Template, I am unable to exclude a salesperson code. The Analysis Column Template is working properly. I am using the <> symbols within the Sales Code Totaling. It will work with one column but not the other. Can someone help?

Which report is this, and which version?
