Question : a problem that get me mad with paginating a partial results

hi
my goal is: a user select a role in a select menu and get the results according to the role he selected.
and then the right results are displayed with pagination.

well most of the work i have done and it works accept the pagination issue. it must be said that the pagination works great if i do not use the filterization.

at the moment, a user select a role ( like a team person) and he get the right result with the right amount of pagination. but when i press the pagination for a certain page, i get a blanck page. no results. so it works great for the first page but not for the other pages of the pagination.

i attach the code that proccess the select menu .

i have tried everything i can think off, but could not find any solution.

best regards

ron
