Solution 1

Try:

"^100(\.0{0,2})? *%$|^\d{1,2}(\.\d{1,2})? *%$"

instead. I removed the '?'s right after the '%'s.

You should try to use Expresso[^] when you come to manipulate regular expressions.

Beware, I updated the solution because I did not notice there where two parts in your regex. Both parts have to be corrected.

Also, the expression allows "100.%", which is strange. The "0{0,2}" should be changed to "0[1,2}" to force at least one digit after the decimal.
