Assign an ID to it and reference it by the ID:

Code:

<input type=hidden name=flag value=0 id=flag>

<script language=javascript>
/*******************
obj: the ID of the field you want to change
val: the value you want to change it to
*******************/
function changeValue(obj,val)
{
 obj.value = val;
}
</script>

HTH,
