5 drop-lists to generate URL

Hi all,

It was not for the want of trying, but I just don’t think I knew where to look or what to search under, which brings me to asking the good people here. I’ll try and keep it short and to the point…

I need 5 ComboBoxes/DropDown-lists/whatevers which are [COLOR=Red]Item[/COLOR], [COLOR=Red]Colour[/COLOR], [COLOR=Red]Height[/COLOR], [COLOR=Red]Width[/COLOR] and [COLOR=Red]Price[/COLOR].

And once the user has selected an item from each dropdown, and presses a button, this will generate a URL in a new window. Something like this:

[SIZE=2][COLOR=Gray]http://www.thewebsite.com/result.asp[/COLOR][COLOR=Red]?item=[/COLOR][COLOR=SeaGreen]DROPDOWN1[/COLOR][COLOR=Red]&colour=[/COLOR][COLOR=SeaGreen]DROPDOWN2[/COLOR][COLOR=Red]&height=[/COLOR][COLOR=SeaGreen]DROPDOWN3[/COLOR][COLOR=Red]&width=[/COLOR][COLOR=SeaGreen]DROPDOWN4[/COLOR][COLOR=Red]&price=[/COLOR][COLOR=SeaGreen]DROPDOWN5[/COLOR][/SIZE]

The second part of my ‘question’ is: Is there a way to, if the user chooses [COLOR=Red]Item#1[/COLOR], then in the [COLOR=Red]Colour[/COLOR] list, 3 particular colours are there, but if the user chooses [COLOR=Red]Item#2[/COLOR], then there a different set of colours to choose from?

If anyone knows how this is done, or knows of a useful tutorial, or even what this method is called so I can continue my search, I will be extremely happy and relieved. Many many thanks in advance for any help given.
