Having trouble with regular expression in javascript not validating when it should

Question

Hello i am trying to validate some form input where the format needs to be.

GBR (Exactly) followed by [1-9] for 1 digit then [0-9] for 2 digits and then nothing else.

I am using it inside some jquery.

            jQuery(function(){
            jQuery("#P3_P_CODE").validate({
                expression: "if (VAL.match(/^\w[GBR]{1,3}[1-9]{1,1}\d[0-9]{1,1}$/)) return true; else return false;",
                message: "Should be a valid Project format"
            });
        });

Meaning that

/^\w[GBR]{1,3}[1-9]{1,1}\d[0-9]{1,1}$/

is my regular expression.

The problem that i am having is that no matter what i type into the input box i am still presented with an error message meaning that my regular expression must be incorrect.

I have tried several different combinations in my REGEXP to no avail.

Any help would be appreciated

/^GBR[1-9]\d\d$/

[GBR] means one of those characters.

I see what you mean :) i have added your changes but it is still not accepting a value of GBR101 for instance. – Paul Cunningham Mar 11 '13 at 18:45
The regular expression works: [example](http://jsfiddle.net/ZMXGe/). What plugin are you using for validation? – a better oliver Mar 11 '13 at 19:09

According to the documentation there is no "expression" option. – a better oliver Mar 12 '13 at 14:26
Ahhh briliant, so obviously no matter what i entered mine would of returned false, my mistake i'll see if i can find a library that includes an expression option. – Paul Cunningham Mar 17 '13 at 15:53
