Compatible types error in UserInterfaceImpl class

[shaneeqa]

In UserInterfaceImpl class, Code Line:
TextField tile = textFieldCoordinates.get(new Coordinates(xIndex, yIndex));

I get an error Incompatible types. Required: java.awt.TextField Found: sudoku.userInterface.SudokuTextField

How can I get rid of this?

I think its just a typo, you have the change the "TextField" to "SudokuTextField".
