Creating a notification to point to the error

Hi Guys, the code below is working; but i need help as i am a newbie and currently working in a programming line which the last time i did programming was donkey years ago.

Ok, spelt out a bit too much sorry, my main concern and main aim for the codes below is that I was wondering if any guys can show me how to point to the location or produce an error message or a notification box to indicate the error:76 that is intermittently popping. because i need to create an error box to show that once an error occurs; how to point to that error location as well as to type a notification on ways to troubleshoot the error.

I greatly appreciate your guys help on this.

Thank you very much for any assistance rendered.

Code:

This question was cross posted and answered on VBForums

Basically the answer is to use an error handler and line numbers then check the ERL value in the error handler and either display or log the info when an error occurs.
