Control boxes and datasheet view in the same form

I am a chemist and I try to make a database for reagents. I also try to make
a form which is based on a parameterized query about the reagent's name and I
want the form to contain a small list box, where the results of the query
appear, and several other control boxes for a more user-friendly interface
for the results. I have partially achieved it, but I must insert the
parameters twice (once for the list box and once for the rest ) and the
selection in the list box doesn't necessarily follow the rest controls (it is
not supposed to happen, is it?).
Can it take place? Through simple steps or through VBE?
Thanx in advance for your help...
