A negative amount may be acceptable - credit note - and a one off price may be a finer fraction, but this example shows a couple of other potential errors. As I have already said ... 'strict' may well only be a subset of the error check. A "numeric" type would introduce the problem of scale of number. Something which any of the database extensions already manage on a field by field basis. -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk Rainbow Digital Media - http://rainbowdigitalmedia.co.uk
