Option 1:
I have 2* sample files on data table in my archives:
*one variable, 2 variable
One variable data table example.xls
http://savefile.com/files/1007074
2 variable data table example.xls
http://savefile.com/files/46276
Take it away & try checking the differences between example (2) above & what
you've set up over there.
Option 2:
If you're still unable to get it going despite the above,
upload your sample file using a free filehost, then post a link to it here
Eg, you could use this free filehost to upload:
http://www.freefilehosting.net/
Copy the "direct link" which is generated after you upload,
then paste it here in your reply
I'm using xl03, so pl save/upload only as this version (if you're using xl07)
I'm not able to open/read xlsx files.
