Thanks Viv,

That's close to what Gregory came up with: "^ *-?\d+(\.\d{2})?$"

>>What I am getting back from this function is the text "we got here" when I pass 208.26 (or any other number for that matter) in. I don't know VB very well, nor the Regular Expressions stuff so would appreciate if anyone could point out why the passed in number is failing the IsMatch check.
