Hi,
can any body help with this script, I need to be able to create a link from the last combo box, ( a submit button would be great!) I have used google as the data for an example just need to know how to get to their site by clocking on a button?. Please just select the "ones" in the menu to get to the last box.

Thanks

Weby.

// This script supports an unlimited number of linked combo boxed

// Here you have to put the data that will fill the combo boxes
// ie. data_2_1 will be the first option in the second combo box
// when the first combo box has the second option selected


// first combo box

data_1 = new Option("1", "$");
//data_2 = new Option("2", "$$");
