Addition flashcards needs a little tweak!

Hey guys!

I am attempting to create a userform that will act as an addition flashcard. All the data from each problem is then posted on Sheet1 aka "Data". Everything is working well, but the user needs to press return twice to enter the answer and move to the next problem. Initially I thought that this was a SetFocus problem, but I haven't had any luck resolving the issue. I have also tried KeyUp and KeyDown; still no luck. Here is my workbook, please take a look! Any ideas would be great!
