missing : after property id using jquery validation addMethod

missing : after property id using jquery validation addMethod

I copied this code and changed the final line "You must the fill in this field." from just "" (blank). The code worked in fine before (in the example) but now I get the error 'missing : after property id' on line one in this case. I checked to see if there was any vars I had missed or anything like that but no. Strange could really do with some help. I am using a jQuery plugin by the way.

I added more code as requested but I don't really think theres anything else I can add. I am using a plugin lib that I thought would be doing the rest. See documentation here.

    }, "You must the fill in this field.");
