Google Analytics Event Tracking not recording numeric label values

Question

It looks like Google Analytics cannot track events with numeric values in the label.

_gaq.push(['_trackEvent', 'Videos', 'Play', '12345']);

Is it possible that GA can't record numeric values? I can't find anything in the GA docs.

At the same time I also use Universal Analytics with the same event. But in Universal Analytics the numeric label is recorded.

Answer 1

The label is always a string. If you omit the label (since it is optional) and put in an integer, then that parameter would be considered the "value" of the event.

Answer 2

The value of the label (for the same event) is not always numeric.

The values looks like: 12345 T12345

The string with 'T12345' is recorded by GA, but 12345 not.
