I know this is not scripting related at all but I'm desperate and i needed somewhere to cry for help. I have been pulling my hair out for about an hour now because this text box that wont let me edit it when I test my game. I click on it and nothing happens, is there something im missing?
Check the properties of the text box. Make sure that the TextEditable property is set to true.
List of things that may be wrong:
-Text Editable Property
-A text Label is different than a Text Box
-Is it in the StarterGui?
