Package Failure - View Details?

[llen]

I am new to PL/SQL Developer and trying to learn all the features.

My question is: I have a Function within a Package that I have executed and has a variable named Result that returns the result of the function. It is failing and cannot seem to see where/how it fails. Is there such viewing of details available? Any advice will be greatly appreciated.

Hi IIen,
Try using "test window", read about it in "help".

Point to package in browser, open it, open functions, mouse right click on function, chose test, enter input parameter values, F9, CTRL-N (step into), ...

Before any testing you must compile it with an "Add debug option".
