Hidden field not associated form

i am using a linked list to enter information

the link passes information ie: ?division=“32”

the new form can use the data from division but when i hit the submit
button the division data is lost in the controller.

if i try to pass the division data via hidden field in the form i get
an error with my new command.

how can i continue pass the ‘division data’?

Can you show the code of view and controller??
