jump to / child report to show parameters section

I have a main report, which jumps to a child report. When that jump to / child report loads, the parameters are hidden.
Customer would like the parameters to be shown, rather than expecting users to click the "Hide/Show" arrow button to set them to visible/shown.
Any ideas on how to do this?
Code behind maybe?
Thanks!

Cant the parms be shown? I think so. In design just uncheck the "hidden" or add them (define them) on the child report and disable the "hidden" property. as long as you have them on both reports nothing has to be hidden.
