My problem is that I have in one page two text fields, if the user knows 
the code (code1 and code2 which represent the values of textfield1 and 
textfield2)he enters them, otherwise,, there is two links beside each 
textfield leading the user to another series of pages and the final one 
returns it to the original page with the selected code, how can I keep the 
value of textfield1, when it returns with the value of textfield2,
in other words, I want to keep the value entered in one textfield when the 
user returns back from choosing the value of the other, at the end I want 
both values to be there?
