Lookup Box Dependency Filters not working.

I submitted this directly to support 3 days ago but as I've not received a response, I thought I would try the open forum. First I'm a creator newby, but none the less...

I'm trying to filter a lookup field based on another lookup field on the same form and I'm trying to use the instructions found here as guidance.

I have three forms which are created as a basis for each of my lookups for my final input form. However for this discussion I will only discuss two input forms and the final data collection form.

On lookup form one called "ProductFamily" I have a single text field called "ProductFamily". For my example, assume that I have entered "Family A" and "Family B" as the data in the input form. See image below...

On lookup form two called "Product Group" I have one lookup field called "ProductFamily" and one text field called "ProductGroup". The lookup data for ProductFamily is the data stored in the ProductFamily form referenced above. The idea is to associate each ProductGroup with a specific ProductFamily from the lookup box. For my example, assume that I have four product groups 2 associated w/ Family A and 2 associated w/ Family B, or...

PRODUCT FAMILY	PRODUCT GROUP
Family A	Group One
Family A	Group Two
Family B	Group Three
Family B	Group Four

See image below...

Last I have a form called "RMA Parts Detail" on which I have a lookup field from each of the previously mentioned forms, "ProductFamily" and "ProductGroup".

I'm trying to create a filter in the "ProductGroup" lookup based on the value in the "ProductFamily" lookup However when I create the filter, for ProductGroup I am unable to get it to reference the "ProductFamily" lookup on the ProductGroup form, instead it appears to be referencing the "ProductFamily" lookup on the ProductFamily form. See screen caps below and final expectations needs at the bottom.

I expect the result when selecting the data in the shipping product group to be filtered by the value in in the shipping product family however the list is blank.

So if I select "Family B", I expect to see only "Group Three" and "Group Four" in my Product Group list (however it is blank)

Please explain what I am doing wrong and if needed, is there a way I can manually EDIT the value in the filter instead of just using the set filter dialog box.
