Message box pop up asking if I want to run a macro which pulls data from another SS

Hello All,
I would first like to tell everybody how much I appreciate this forum. I have gotten the best help and I have learned so much by looking at other post. The experts on this site are the best!!!

My question or plead for help is... I have a master spreadsheet (sheet1) that I have a popup box that asks if I want to run the macro. The macro is deleting all from example 1 then goes to example2 and copies data and paste the data on example1. I am getting an error when it gets to this code

Windows("example2.xlsx").Activate
