Hi Paul, I apologise for the confusion. You are right I did not fully comprehend yet what you were proposing, so was probably early in forming an opinion on part of it!
Let me briefly describe the situation I want to accomplish. 1) I have a sheet of data that I run a macro on. 2) At a certain point, let's say after 20% of the code has already executed, I will want the macro to call up a message box of unique locations (I have no problem getting the list made & removing duplicates) 3) The user will scroll through box, clicking a check mark next to the ones they want to select. 4) They will then hit the button in the message box, at which point the code will continue to the next step, which is deleting any record with a location matching one of the checked ones. Question: are the two sub() you proposed complementary, and I need to integrate both of them, or are they two different options for the same thing? As I mentioned on Friday, this is completely uncharted territory for me. Thanks again!
