I want to do a validation of my checkbox so that the only valid values that are allowed are
a to z, A to Z, aa to zz and AA to ZZ.

i am using the following code to acheive this:

But it is displaying the alert message even if i enter a valid value like 'aa'?

Can u tell me where i am going wrong?? I want to know if my reference string is given properly?

Thanks in advance.
