Validate format of values

Client is using WinXP/Office 2003.
He has cells with Canadian postal codes. The postal codes should be 6
characters starting with a letter and then alternating every other with a
number. For example, V2L3M4. He would like a formula to evaluate the cell to
determine if the postal code follows the correct syntax. Any ideas?

Hello Maryj.

If your zip code is in A1 you could use this formula:
=AND(ISNUMBER(LEFT(A1))=FALSE;ISNUMBER(MID($A1;2;1)*1);ISNUMBER(MID($A1;3;1)*1)=FALSE;ISNUMBER(MID($A1;4;1)*1);ISNUMBER(MID($A1;5;1)*1)=FALSE;ISNUMBER(MID($A1;6;1)*1);LEN(A1=6)
)

It checks each digit to determine whether it is text or number.
