That looked like it would do a good job of cascading to all reports. A couple of questions:

1. Where would I put it? It didn't seem like it could be worked into the report expression field. I will try placing it in the click of the report's command button.

2. Is there anyway this command would inadvertently put my replacement characters in the null fields of the table? "Display" doesn't sound like it would but I don't want to assume anything.
