Comparison of two dates

[mallz]

hi,
i need to do a comparison on 2 dates. Im using this:
if (Date.parse(tdate) < Date.parse(fromdate))
{
alert("Invalid Date Range!\nStart Date cannot be after End Date!")
return false;
}

On click of a save button, im using onFocus event to validate this, but it is not working.It is not validating it.
What could be wrong? Please help.

What element's focus event are you using, what does it do onfocus?
Why not validate when the fields change, or immediately after you click 'save' ?
