Problem:

Column A (List1) is formatted to display a leading zero before each number. That is, \"1\" is displayed as \"01\", \"2\" as \"02\", and so on.
The following formula was created to concatenate the numbers from List1 into one string:
=A2&A3&A4&A5
However, an incorrect result of \"1234\" is returned.
How can we modify the formula to honor the leading zeros?

Solution:

Use the TEXT function as shown in the following formula:
=TEXT(A2,\"00\")&TEXT(A3,\"00\")&TEXT(A4,\"00\")&TEXT(A5,\"00\")
