Custom Fields Script Variables

Hi,
I am trying to insert custom fields into the script tab.
Custom fields are currently filled out in the form as normal. I want the information from those custom fields to appear in the script for any future calls to this customer.
I have tried --A--Homeower--B-- (this is one of my custom field labels). it doesnt work, script just displays "--A--Homeower--B--"
Is there a way of doing this?
Can anyone help here or is it not possible?
