I want to create a regular expression where only numbers are allowed with max length 9 and no minimum length. I came up with d{9}[0-9] but it isn't working.

You're close. Try this:



^d{0,9}$


The ^ and $ match the beginning and the end of the text, respectively. d{0,9} matches anywhere in the string, so d0000 would pass because it would match the 0000 even though there is a d in it, which I don't think you want. That's why they ^$ should be in there.
