Getting Application Error that reads:

The instruction at "0x77c2a573" referenced memory at "0x00000003". The
memory could not be"written"

Click OK to terminate the program.

I am running ADO/VBA script in Excel. When the scripts are done I close
Excel and it gives me this error. Below is my code. Thank you.
