In my email template below everything works except those highlighted in blue.

I would like to know how to get the phone , user name and Original Account ID Number into my template.

Dear Sam,

Our reference: ${Cases.Account Id Number}

Can you contact him/her on telephone number ${Cases.System NMVS contact Phone}

The user ID for the Practice /Pharmacy /Hospital /Wholesaler is: ${Cases.System User Name} ${Cases.System Original Account ID Number}
