Problem reading numbers from spreadsheet using Outside In Content Access

Hi

I need help on using Outside In Content Access. I can read spreadsheets using a function called CAReadNext, but the problem is that it skips reading pure numbers. I saw the documentation, it talks about using a special content type SCCCA_GENERATED but I do not get this type while I iterate through the spreadsheet. Is there any way I can pure read numbers from spreadsheet?

Thanks in Advance!!
