What oldbrewer was trying to get you to do is use the TEXT function on each of your original cells...
=CONCATENATE(TEXT(A1,"00000"),TEXT(B1,"00000"))
Just so you know, instead of using the CONCATENATE function, you can join text using an ampersand between them, so to join A1 and B1, instead of writing this...
=CONCATENATE(A1,B1)
you can write this instead...
=A1&B1
Applying that to your question, the first formula above (the one I say oldbrewer was trying to lead you to) could be written this way instead...
