New Post: Getting Content Type within EditForm.aspx

The reason why I ask is because I have my three lists set up that I use for my cascading. The first two lists are the same are the same regardless of the content type. However, the values that should be available in the 3rd drop down should be filtered based on the Content Type selected.

Data structure in List 3. Based on the Content Type selected I want to use a CAML Query to only select the fields associated with that "FileType"

Title             SubSection                                      FileType
1.1.1 PR          1.1 Purchase Request Documentation              Contract
1.1.2 Property    1.1 Purchase Request Documentation              Contract
1.1.3 AAP         1.1 Purchase Request Documentation              Contract
1.1.1 ABC         1.1 Purchase Request Documentation              DeliveryOrder
1.1.2 DEF         1.1 Purchase Request Documentation              DeliveryOrder
1.1.3 GHI         1.1 Purchase Request Documentation              DeliveryOrder

So the scenerio would be that I already have a document set created. I go to "Upload" document. When I upload the document, I'm eventually brought to the metadata form. This is where I have implemented the Cascading Dropdown menus. However, the last requirement is to filter the last list based on the content type selected. Below are how examples of how the data would be represented if I could get the filter to work correctly on the last dropdown menu.

Example 1:

Content Type:  Contract
Drop Down 1:  1. Pre-Solicitation
Drop Down 2:  1.1 Purchase Request Documentation
Drop Down 3:  1.1.1 PR
              1.1.2 Property 
              1.1.3 AAP

Example 2:
Content Type:  Delivery Order
Drop Down 1:  1. Pre-Solicitation
Drop Down 2:  1.1 Purchase Request Documentation
Drop Down 3:  1.1.1 ABC
              1.1.2 DEF
              1.1.3 GHI

So I need to figure out how to get the Content Type from the dropdown menu on the EditForm.aspx. As I mentioned above, I've tried to use the jQuery and Javascript, but my syntax must be incorrect.

Does this make sense of what I'm attempting to accomplish?
