Repeat Trial

[liwenna]

Oi... I justed wanted to expres that I agree with Paul that the two
input masks solution is really elegant!  I'd have never thought of
that, and always script in the jump to the label (then again I also
think that whenever I use this I also use the string hittest and
therefore could not use the inputmasks).
