modify a parameter's value

Former Member — Fri, 22 Aug 2008 09:40:09 GMT

i have 2 parameters on my selection screen, p_file and p_file2

I am retrieving the path for p_file

and p_file2 copies this path.

after, if the user wants to modify the path in p_file2, there should be a popup to confirm if he wants the path to change

I was able to retrieve the path for p_file, p_file2 copies p_file but I cant cater for the change in path for p_file2.

see my code below

plz help
