Navigating a recordset 2

[AndyApp]

HELP

I have built a recordset using asp which is at the top of the page, the rest of the page loads and I need to give the user the ability to move to the next record.

I have tried using a button that calls a function that uses the oRS.MoveNext function. But it doesn't work and just says 'oRS' (my recordset) is not an object.

Surely this can't be that difficult to make? If anyone nows how I can use the DTC navigation thingy that would work too.

Seems an awful lot of code to do something that I would have thought would be simple but it does the job and i'm happy.
