It’s also visible when it’s collapsed.
Should be noted it’s playing under a loop. But I placed it outside the loop and still get the blue marker.
Hover over the blue error marker with your mouse and see what it says. This will help you determine the issue.
If you do not understand the error or how to fix it, tell me what it says and I can help you out.
The issue is that you are trying to set the text to an underscore , which cant be in this case. Try to replace "" with “i” or any other letter.
And so with your print and other stuff in there.
In such cases, it’s preferred to use “i” or any letter rather than an underscore.
