I dont know how to word this, but heres my code:
questionDescLabel.Text = quizSettings.questionsSettings.questions[number].desc
How do I add a string to the end of this?
You need to concatenate two strings together. You can do this by using the concatenation operator, ..
An example is:
“Hello “ .. “world”
which would return “Hello world”
