setProperty() value parameter value () is not a uistring. setText() text parameter value () is not a uistring.

The problem is that outputString is a list and not a String. You need to create a string and concatenate all the items from the list into the string and then set the text to that string. ---

How does one do that? ---

> **[Check out what I made](https://studio.code.org/projects/applab/-pxR9kj1ELVM-EvQ-9xSv75pFmjUxjr_YrTW5G6OFOQ)** > > I wrote the code myself with Code.org There were a couple of issues, the biggest was how you were testing in your conditional. Remember, you need to test a specific index in the list, not the list itself. **list[i] == something** I moved some of the other structure around to make it a little more efficient. You were getting a unistring error because you were not passing anything along. Let me know if you have any questions. ---
