Conversation with links to previous and next conversation within the same channel

[fluo66]

I am fairly new to VB5 and just started migrating a VB4 to VB5 forum. It seems that the template construction and programming language changed a lot.
In the current VB4 version of the forum a very much appreciated functionality is to navigate to the previous and next conversation from within the current conversation displayed.
So I am now looking for a way to place at the top of a conversation page two links/buttons to the previous and next conversation within the same channel.
But until now unable to figure it out how to modify the templates. After spending a lot of time on google, I hope someone of you is able to point me in the correct direction.
