Sort order in catalog variable list collector

[jcwarren]

We have a service catalog list collector variable created from a select box using the procedure outlined here; https://www.covestic.com/blog/servicenow-tips-making-list-collectors-useful/. 

We want to sort the resulting list collector options by the Order value from the select box choice list instead of alphabetized as is the default. 

We've tried the ref_ac_order_by=<fieldname to sort by> Community solution provided here without success.

Any assistance would be greatly appreciated.

Thanks in advance.

Attribute ref_ac_order_by applicable to Reference variable. Refer Service catalog variable attributes for more details.

Thank you for your reply, Periyasamy. There was no mention of the variable type in the community thread I referenced but I should have looked that up.
