ctrx_get_server_name returning blank

Hi,

We are running LR 11.52 on a Citrix environment (Citrix receiver agent ver 13.4.200.11) and want to capture the Citrix Server name the user logs-onto, into scripts already proven and running without issue.

To do this, we coded the Ctrx_Get_Server_Name function into the script, however, when run the function returns a blank value rather than the expected Citrix server name.  Any assistance / guidance on either how to get this function to work, or an alternative way to capture the server name, would be much appreciated.

It should be noted the LR Citrix Server agent is not installed.
