if nothing selected geturl 1

[thompom]

hi,

have a combo - when an option is selected and a search button is clicked it goes to a page, however if nothing is selected i want it to go to another url

this is the code for the button

thanks MG

on(release)
{
makeselect = makecombo.selectedItem;
priceselect = pricecombo.selectedItem;
                   
if (makeselect.data == "undefined") {
getURL("3coltemp.asp?pagesetupid=2&cmd=resetall", "_self");
} else {
getURL("3coltemp.asp?pagesetupid=2&x_make="+ makeselect.data +"&z_make=%3D%2C%27%2C%27&x_price="+priceselect.data, "_self"); 
}
}

if (makeselect.data == undefined) {

no quotes around undefined as its not a string

thanks v much
can you tell me why i get this error

**Error** Symbol=page 1, layer=searchbut, frame=1:Line 17: Left side of assignment operator must be variable or property.
     if (priceselect.data = undefined && makeselect.data = undefined) {

on this line

if (priceselect.data = undefined && makeselect.data = undefined) {
usedurl = usedurl + "&cmd=resetall"
}

for comparison you must use == and not =
