Displaying multiple values

That worked! Thank You!
Now, I'm having another problem, if the value of T2 is "01", only "1" is displayed. I have used the format cells > custom > 00 but it still doesn't work... I would like it to display a LETTER LETTER DIGIT DIGIT LETTER always, whether there is a zero or not. I have tried to enter ##00# but that doesn't do the trick
