Just looking for some help on how to create a javascript that will check for a comma in a textbox and on submit or when the person goes to a new field that it will throw a warning to not use a comma in their value.  This is for currency, so many times, people entering values from Europe will enter in 23,99 instead of 23.99  and I also do not want 1,599.99 or 1,599,99
