Hi,
It is a correlation issue. Please review the correlation chapter in LoadRunner guide and the following documents:
1. What is correlation and how is it done

2. Webinar - The Art and Science of Correlating Web Applications available from the following document:
http://support.openview.hp.com/selfsolve/document/KM198688
You will need to add a valid SAID to your HP Passport to view the document.
You can find instructions in the following link

As LoadRunner 8.0 is not supported any more I would advise you to upgrade to a newer supported version LoadRunner 11.x or 11.5x. If you decide to upgrade the licenses will need to be reissued.
Kind regards,
