Duplicate a Box depending on how many rows another tab has.

I need a macro to duplicate a box i have in a sheet depending on how many rows the other tab has. In this example file ive included the macro i have now. With this macro i select A1 : R23 and press ctrl shift d, it asks me how many duplicates i want and i enter the number based from how many the test2 tab has. I would like a macro to read how many rows the test2 tab has and then automatically duplicate the box that many times . In other words automate it, instead of me having to enter the number ( this number changes depending on the file i have ).

Ive included a test file with intructions and my current macro, i have 2 tabs which need to be looked at.


Thanks for any help.
