I uses "Get a row" to grab the data from the another table called "Service Line", and liked to display the text value of the field called "ts_name" as the output in email body. Please see the steps and expressions used in the steps below. However, nothing is displayed in the email body.

In the output of Get a row, the name "Tax and Accounting" shown is the output value I wanted to display in the email body.

Any suggestion is appreciated!
