master detail page - move specific record detail page

I am trying to create a master/detail page set whereby I can click on a link on the master page and go to a detail page to display more detail of that record.

I have acheived this without problem.

However, what i need is to be able to page through the detail page as well, instead of just filtering the recordset on the one item.

I have now built the master and detail pages with identical recordsets.

I need to know how to make the detail page 'move' to the correct position in the recordset, when the corresponding item is clicked on the master page.

I'll be passing an url parameter called 'itemid'.

Any help would be greatly appreciated. Including advice on a different approach if i am misguided in my effort and there is a better approach.

Thanks,

Ben
