In the included piece of code, I have made an administration panel for our County Directory. When a user logs-on, they will be able to choose from a number of options in a drop-down box...
When I choose an option (during testing) and click 'Submit', the page is directed to itself...It doesn't go anywhere....
But when I choose the option a second time, it directs to the correct page...
Why is this happening?
In my code, I am using sessions to set variables, and I suspect this may be the reason why I have to double-click...Any and all input is appreciated!!!
Thank you all in advance for your help!!!
Mike
