I searched a lot and can't find the solution for this RegExp (I have to say I'm not very experienced in Reg. Expressions).

I would like to test a number between 1 and 36, excluding 0 and 37 and above.

What I've got so far and almost works (it doesn't accept 17, 18, 19, 27, 28, 29)...

```
^[1-9]{1}$|^[1-3]{1}[0-6]{1}$|^36$;

```

Can someone help me please?
