Thanks for your patience I still can't figure it out. I now know how to make the event, but how do I make it work this way:
1. Whenever enter is pressed the TextBox.Text is read into the global variable "input" (this already works)
2. Also whenever enter is pressed the value of "input" is compared to the words in the array (I think I got this too...)
3. If the input does not match with the array -"Syntax error" in one of the text objects.
Sorry :/
