I need your help,
I cannot, for the life of me, figure this out. I've had my head wrapped around it only to no avail. Ideally, i'd like to setup two functions. 1 function: select_date() to interact with the user to select a date from the jQuery Date picker. If the dialog is closed then return as null. Then a second function: test() to check wether or not a date was picked/selected.'
Here's my delema, when the function test() is executed, an alert box pops up and says "undefined" which means, I never get to select a date and it always being "undefined"
I dont see what I am doing wrong here and everything seems logical to me.
