Limit-number-of-repeat-groups does not work

Hello,

Url: CMB2-Snippet-Library/javascript/limit-number-of-repeat-groups.php

I report that the CMB2-Snippet-Library/javascript/limit-number-of-repeat-groups.php script currently generates an error.

By executing an alert: alert("fieldGroupTable = " + fieldGroupTable);

I get the error back:
VM2670 post.php: 777 Uncaught ReferenceError: fieldGroupTable is not defined

WP 4.9.4 - CMB2 2.3.0

Thanks, Claudio
