MS Access 03: Multiple Subforms

Hi All, quick question for you.

Is it possible to have two subforms within a form, where you chose which entry to view in the second subform from the first subform (if that makes any sense)?

I've created a form for entering generic set information, I've then created a subform which gives a list of all the equipment within that set (for example you might have a list of weights, which will show the serial number (if there is one - note: this is not the primary key), the denomination of the weight and the prescribed limit of error for the weight, this form can't be altered or added to - the primary key is included in this list, but it isn't visible. I then have a third subform which shows more in depth information regarding the weight. At the moment the subform will show all weights in the set, individually as you click through the records using the navigation bar. However, I would like to be able to click on a particular weight in the list and have the information regarding that weight displayed in the subform below.

I've been searching round but so far am struggling to find anything. I would appreciate a point in the right direction.
