How would I create a cascading drop down box for access database?

I creating a CRM to work in.  Its nothing robust.  And it doesnt need a lot of fancy features or anything.   But what I need is to add a cascading combo box.  So in box one I will list what criteria needs to be shown in drop down box 2.  

The two drop down boxes are at the top left of the contact form under the general tab.  

Another example.   In box one I will have a list of categories that pull from a table.  It will list things like month.  Then if I select January,  in the second combo box it will pull up the list of people who fall into the january category. If I choose March it will pull up the people that have the march keyword assigned to them in the second drop down box.  Then what happens is based on selecting the name in the second combo box.  All their information will show in the form I created.  

Unfortunately,  I am a beginner.  I would not even call myself an access database designer.  So as much as you can give would be great.  I attached the database.

You should have any relation between two tables. In [CG Info] you have Targeting field, but it is empty. Fill it and you will be able to make cascade combo boxes. Look at sample. Select January or February or do not select anything
