For Counter = 1 To Len(ActualWord)
LetterPos = InStr(Counter, LCase(ActualWord), Letter)
'if the letter was found past the current
'position, then
If LetterPos >= Counter Then
'display the letter in the returned value
DisWord = Left(DisWord, LetterPos - 1) & Mid(ActualWord, LetterPos, 1) & Right(DisWord, (Len(ActualWord) - LetterPos))
