function mw_toCurrency (value,decimalPoint) {
if(isNaN(parseFloat(value))) {
return;
if(!decimalPoint) {
decimalPoint=",";
var newValue = "" + Math.round (parseFloat(value) * 100);
while (newValue.length <= 2) {

var valuepays = parseFloat(vrpays.value);
var finalvalue = (valuepays * numberpays)
finalvr.value = mw_toCurrency(finalvalue,",").substring(0);
</script>

Answer 1

You could change your block into a form, and call it with call_form. By that execution would halt in the calling form when you open your "block".
