passing parameters in oracle web server 2.1

i am using Oracle Web Server 2.1 on NT 4,PLSQL agent and WRB.As part of the project there is a small module where the user first selects the columns of a table on which he wants to do a search(this is done using checkboxes).Then he is presented with only the columns he selected alongwith textarea boxes.here he enters the string (varchar2) that he wants to search for in that particular column(s). can somebody tell me how to pass the strings the user enters in the second page to a procedure which does the query and returns all the records containing the entered strings? thanks in advance shivs shankar
