Project VBA Debugging

Question

I am modifiying some Project 2010 VBA modules that I did not write. My predecessor wrote a bit of code that catches an error, outputs the error message (and just that, no specifics compared to run-time or compile errors Project would catch) and ends the
function. Is there a way to modify the following code to provide more description, such as line number, the problem variables, etc.?
Err_cmbMapNow_Click:
    MsgBox Err.Description
    Resume Exit_cmbMapNow_Click
I think the problem lies in an If statement that checks the file's type against whether or not it's an Enterprise-type Project. The error I'm getting is "The argument is not valid". I tried enforcing them to be Integers so the If statement is comparing
integers, but that doesn't seem to work (if this statement is the problem). When I debug it, it stops at that statement and won't continue.

Mr. Lee,
The problem with error messages is that generally they cover a wide range of possible causes so to the average, or even advanced user, the messages are essentially useless.
Paul is correct, in order for us to help you we will need to see your code. In particular the "If" statement that is being flagged with the error and any other lines of code that provide arguments to that statement. It could also be something as
simple as an incorrect declaration. For example, a variable that is declared as a single (i.e. number) but is being used as a string (i.e. text).
