Hello, My students have been working with Hackathon project for a few days. I have had quite a few students with the same error. “WARNING: Line: 35: setText() text parameter value (undefined) is not a uistring.ERROR: Line: 35: TypeError: Cannot read property ‘toString’ of undefined” At first glance their programs look fine. I’m a decent at programming and I’ve been able to find most errors to help fix, but there are still a couple that are elusive. I have gotten better at finding errors, but I’m spending a lot of time trying to find the reasons and then the fixes. I’ve Googled the warning and the articles I’ve found are not very helpful. Any suggestions on pinpointing the error to save a very tired teacher some time. Thank you.
