i use a similar technique rapped all up in a nice function....
i think ive posted this up on one this forum before. and i don't mind sharing this piece
/**
* This passes three important pieces of information between page calls, the current page we wish to view, the total number of results, and the numberof results displayed on each page
*
* it is up to the recieveing page to determine defualt values for the first call to this function, as well as use this info passed to actually retieve and display each results, this only gives you the menu, but should give each page enough info to determine what to do
