Hello Chuck,
We are glad to know our software works for you. You can use the
following script:
for(;;)
{
var v = event.change.replace(/[^0-9\-]/, "");
if(v == event.change)
break;
event.change = v;
}
Note that [^0-9\-] is a regular expression. You can google for its
syntax. Basically that statement means if the input character is not
between 0-9 or "-", replace it with empty string.
Thanks,
