OK, I did this :
strDBC_B_Expiration = "02/2003"
strDBC_B_ExpirationMonth = left(strDBC_B_Expiration, 2)
strDBC_B_ExpirationYear = right(strDBC_B_Expiration, 4)
Response.Write "Month = " & strDBC_B_ExpirationMonth & " Year = " & strDBC_B_ExpirationYear
And it worked fine, so maybe it is the way you are receiving it from the database?
If it is a true date, you could extract the Year, Day and Month anyway, even the name of the Day using the VB Sunday function
