How to set a fieldname as action_result when it has a dot at the end like No.

In many cases a fieldname contains a dot and I want to present the value in a message.

I am using the function “Choose From Table” and one of the fields is “No.”.

Then to display a message when a line is selected, I want to show the field “No.”.

Therefore I have to set a variable: set Carrier_No to action_result.No.

Except “action_result.No.” does not displey anything, probably because of the dot at the field “No. ”

How do I need to set the action_result?
