The example &#39;var1 = var2&#39; should cause the NameError exception. <br>&nbsp;&nbsp;&nbsp;&nbsp; &quot;NameError: name &#39;var2&#39; is not defined&quot;<br><br>You might want to check your &#39;error log&#39; objects for the error messages. If you don&#39;t have an error log object, it might be a good idea to create one.
