You won't be able to do it this way as, as it stands, you are trying to compare
two *strings*. You need to convert them both to JS time/date objects first.
Here's a function that should work:
[<code>]function checkDateFollows( dp1, up1 ){
dp1 = frm.FieldA.value;
up1 = frm.FieldB.value;
ds1 = dp1.split('/');
ds2 = up1.split('/');
d1 = new Date();
d2 = new Date();
d1.setFullYear(parseInt(ds1[2],10));
d1.setMonth(parseInt(ds1[1],10)-1);
d1.setDate(parseInt(ds1[0],10));
d1.setHours(0);
d1.setMinutes(0);
Mr Paynter,
I take it this means you have a job then?

return ( d1.getTime() <= d2.getTime() ); }[</code>]
Which you would call from anywhere in your script like so:
[<code>]if ( checkDateFollows( f.DateA.value, f.DateB.value) ) { alert("The Date B can't be before Date A"); f.DateB.focus(); return false }[</code>]
See you soon, Jake
