if(a.value === undefined || a.value.length>37 || 
        b.value === undefined || b.value.length > 256) {

If the first one is undefined or greater than a length of 37. I get a error, but it does not check for the second field at all.

    You’re forgetting what an OR in logic means. It only going to check until it finds one true statement.

    Try regrouping:

    ((a.value === undefined || a.value.length>37)
                       ||
     (b.value === undefined || b.value.length > 256))
    

    Just about elevating the condition a bit, and bringing a more broad result back instead of chasing the first true response.
