The user enters a 2 digit number for the month on the form. I check for a length of 2 and for being between 01 and 12. I also check to see if it is a number.

Can anyone explain to me why .1 fails the num check BUT 1. DOES NOT FAIL THE NUM CHECK? It doesn't matter what the 1st number is, a period in the 2nd position does not fail the num check.

I'm just curious

Thanks

Andy,

If I read your validation correctly, a .1 fails because it is less that 1 (and you are checking for values between 1 and 12). The 1. is accepted because it is a) a number, b) between 1 and 12, and c) it is two digits in length.

Wouldn't an integer and range (1-12) check be better for you? That way the decimal points will never be an issue.

It is because .1 is less than 1 - that is why that value would fail.

1. - 9. would all pass the validation because they are between 1 and 12 inclusive.

Thanks Don

I never thought of integer and range. I figured that num check should do the trick.

Silly me.

Hi All

You will be thrilled to know that engineering notation numbers also pass the num test eg 1E1 is 1 x (10 ^ 1) which is 10 and would have passed the original test…
