Ahh, you asked the right question. the reference is to a dynamic range of cells that have the same values in this particular usage. If I that's Why I'm modifying my titles to include "code". I need to take a better look at how I want to use this maybe just manualy edit the titles in this case.

BTW if I reference a sigle cell in the name formula then
.ChartTitle.Text = "Configuration " & Range("CODE") & " DC Resistance"
works fine.

Thanks for helping me clear up my problem.
