Get help debugging code. Want to get round the displayed number in an app to 2 decimal places

Need help to have the display discounted price rounded to two decimal places. I see the rounded number in the console.log but not on the Apps display screen.

Link to the project or level: [replace with link to the curriculum or get the “Share” link to a project]
What I expect to happen: [Displayed discount will be rounded to two decimal places. I see the rounded number in the console log, but on the test display on the app.]
What actually happens: [Rounds to two decimal places in console log, but not in the display text area.]
What I’ve tried: []

The simplest fix i found was changing line 12 to mimic the console.log
code: setText("discp", discp.toFixed(2));
Changing this shows the discount price as rounded. I will also suggest changing text_area2 and text_area1 to read only in the design tab so the text cannot be edited while running the app.
