Hi Mike,

A question that has been wracking my brains is how to get the working?

I need to show the dropdowns on the homepage and then the search page, so i put the variables in the url and take them to the search page and use them to show the dropdowns with the selected values.

Any ideas?

Cheers

Stuart

Dear John,

Regarding my previous post, I have now managed to get them to work but I am having problems with the Javascript. It does not seem to populate the feilds.

Thanks Again

What error codes are you getting? Do you have this deployed somewhere so I can see all the errors you are getting?

My previous post for sucess.php did not contain the start of the code so here it is:
=0;i–)

Sorry about the mess of the comments I have caused but hopefully you will be able to understand them!
Thanks

Sucess.php:
=0;i–)
{
selectbox.remove(i);
}
}

function addOption(selectbox, value, text )
{
var optn = document.createElement(”OPTION”);
optn.text = text;
optn.value = value;

selectbox.options.add(optn);
}
