Asign a value to a hidden field

[crabgrass]

Given the following:

<SCRIPT LANGUAGE="JavaScript">
function GetTIPID(){
var newID;
newID = prompt("Enter ID", "ID here");
alert(newID);
document.myform.hiddentip_id.value == newID;
alert(document.myform.hiddentip_id.value);
}
</script>

the last line reveals that the line before it did not work. Is there something wrong with this syntax or method?

Thanks.

Thanks. I had started with a simple = but got it changed as I was trying to fix other things.
