regex

@vacationrentalsAug 24.2004

Hi guys,

I want to make a javascript with a regex that gives an alert when NOT entering the following (price) format:

XXXXX.XX

whereas the part before the comma is a number with 1-5 digits and the part after the comma a number from 1-2

alternatively the input can be just the part in front of the comma, but without the comma itself.

Cheers
