Joining Static and Dynamic Text
Now we're going to use Dynamic Value again to display a message to the app user. We want to summarise their order details using a read-only Text field.
Add a new Text field to your Form, set the Data Name to be "orderSummary".
Find the Read Only property and tick the box.
This will make the field read-only, so the user cannot change the displayed answer text.
Find the Dynamic Value property and enter the following formula:
CONCAT('You ordered ', {{numberItems}}, ' of ', {{productName}}, '. Total (including tax) is: ', {{totalIncludingTax}})
What we're doing with the above formula is building up dynamic text, by concatenating together pieces of text.
The CONCAT() function is used to build up the final text, and we are using the values from the various fields (the {{dataName}} bits).
