Hello All,
I have been working with a part of my project today, and I have been stuck with what might be something simple---I really don't know...
I have a login form, which will accept a username, password, and department. Upon logging in, control will set those items as session variables.
When I test this script, everything works fine...(Error checking works, it connects to the database and authenticates, and it produces the right message).
When a user is logged in, they have access to the drop-down box, which will allow them to link to 5 different pages...Problem is, when I choose the option and click 'submit', the page simply reloads itself. When I click 'Submit' a second time, it directs to the correct page.
Why in the world do I have to click 'Submit' two times???? This is a real project that will be in use, and I need all the help I am able to get!!
Thanks so much!!!
Mike
