Arguments and Vars want their own name!
ColdFusionAs ColdFusion is scope based its possible to have a form, request and session variable with the same name. I would advise against this wherever possible as it can make debugging very confusing. Arguments and var scopes can not, however, share the same name. And when they do the (somewhat confusing) error will appear:
Cannot declare local variable userID twice.
Local variables cannot have the same names as parameters or other local variables.
The fix is rather simple simply change the name of the argument or the var!
Here is the code that gives the above error:

Oddly enough I just experienced this for the first time last week. What really shocked me was not the behavior, but rather the fact that I had never done that before!

Are you sure this is an issue? I would think as long as your scoping your variables the argument scope would contain the argument and the other would be in a local scope. That is, I would think would solve the issue.
