No Record Display after Click

In my form, "Form1" (which link to a query), there are 2 command buttons. 1
is to run the query and the other is to return to switchboard. When the query
runs, it open another form, "Form2" (which display the filtered record which
I entered in Form1), has 1 command button which closes Form2 (the active
form) and return to Form1 for another new query.

My problem now is whenever I'm back in Form1 to enter another new query, the
result in Form2 is blank. Why is this? How could I overcome this issue? Here
are the codes:-
