Application-Defined or object defined error 1004 When ran on exel97 but not 2003

Hope I am posting in the right spot, if not yell at me and let me know
where I should post at. I'm developing a multipurpose application and
part of it needs to insert some data into an excel sheet. It runs fine
on my machine which has excel 2003 but when I run it on a computer
with excel 97 I receive the Application-Defined or Object-Defined
Error 1004 message. This is where I am getting my error:

oXLSheet.cells(y, 2).Value = rs("Mon" & x)

In this line the first time it is run y has a value of four and x has
a value of 6. rs("Mon" & x) returns an interger value of 6. Prior to
this line i've inserted numerous things into the excel sheet with no
error what ever on either excel 2003 or excel 97. I have it view the
sheet and I see everything get inserted but when I hit that line I get
the error. It is the first place in the code where it pulls a value
from the database.

Any thoughts? I'd greatly appreciate it! I have put the code in full
below.
