custom HTML Views

Hi,

I've asked this question, but seems I can simplify more to get an answer (that I really need here).

When I create a Form for "Tests" with a lookup field:

Label Name: Project
Import Date from: Project -> ID
Display type: Dropdown
Advanced Display: displayed as "Name" property for example.

Then I want to process a custom HTML view for "Tests".

with params:

params='zc_Header=false&zc_Summary=false&zc_EditRec=false&zc_SecHeader=false&zc_RecSelect=false&zc_Footer=false&zc_ColMenu=false&Project=<%=Project_ID%>'

Why is it I cannot filter the "Tests" view by Project by passing the Project_ID?

Isn't it supposed to check against the ID for the lookup field?

Thanks again for any response.
