[Javascript] Regular Exp

[Laurent Muchacho]

Hi Hakan,

Thanks a lot for this help this work much better. I'll try and have to make
it work before going in holiday tonight then I might do an ugly if else
statement anyway and will try to make it work later.

Thanks Laurent

Laurent,

I'm a bit stressed at work now so this might be getting ugly, but you 
could try this change. It should accept one or more numbers, one or no 
dot and then zero to two digits. Hardcore regexp ninjas might see that 
this probably also accepts 1000000000000000000000000000.33 but it's as 
good as I can get it right now.

var number_re = /[0-9]+\.?[0-9]{0,2}/;

Regards,
H
