So - your second expression has 5 digits at the end, and your sample value has four (3454). If I add another digit to your sample value, using your second pattern, validation works as anticipated.... I'm wondering if you are using "and" or "or" in the validation conditions? The condition is that the field does not match the pattern, right? So you'd need to use and there - if it doesn't match both patterns, then it is invalid?
