Does anyone have a function or way to verify a dollar amount that has
been entered into a field?  I'd like to check a pattern such  0.00 -
9999999.99 and make sure they don't put in a $ symbol.  They also need
to put in a negative dollar amount such as -12.36 .Any help would be
greatly appreciated.
