escaped url (variables) in a banner

[Nett77]

Hi, I have a banner which lets you put in your postcode to find your nearest
meeting. I have two varibles which are added on to the url. My code currently
is this:
findbutton.onRelease = function() {

getURL(_root.clickTag+"?href=http://www.mydomain.co.uk/util/gmf/gmf_search_resul
ts.aspx?pg=0&s=ZIP&z="+_root.post+"+"+_root.code, "_blank");
};

However the guys distributing the ad say that the url (inc appended
variables) should be escaped (all or just the variables) before being
concantenated with the clickTAG variable.

It may be a silly question, but how do I do that?

Many thanks
Lynette
