Command Button will only input numbers and not Letters

[GBOOM03]

I created a command button on a form to update a text box with a letter. Although it works when me.studentanswer = 1 It will not work when I use me.studentanswer = A
The text box is set to text value and not number

Have you tried me.studentanswer = "A"
