Issue map prompts to properties

Hi,

I am trying to create a new user account runbook so it can be used in the Self Service Portal. I start my runbook with an initialization of data and the following details:

I have created my Service Request template and my Runbook automation activity template. In my Request Offering, I can map LastName, FirstName, etc., but I am not able to map Branch. What could be the issue? I need to know in which branch they work and I want it to be a simple list so they can choose from it.

Please let me know if more information is required.

Thanks for the help 🙂
