Combo box help

[msi.dhaka]

Hello
I'm new here and this is my first post in this forum.

I created a flash form for simple reservation which contains few textbox and 3 combo box. here is both the fla and php script. http://www.actionscript.org/forums/a...1&d=1220101847

The problem is when i change the value of time cb field then it doesn't send the form. if i dont touch the time cb then it sends the form. I couldn't understand why? Please someone help me. its urgent.

And if possible then please give me direction where i can learn more about flash and actionscript.

Thanks.
