Formula URL Button to Open Specific Form Being Controlled By Role Form Settings

I am trying to create a Button that opens a specific form from a table within my app.  I change the "fid_XX" to any of the form ID's and it doesn't matter.  The form roles are overriding what form opens and opens the form designated in the Form Roles section.  Here is my current URL for the button:

URLRoot() & "db/" & [_DBID_NOTES] & "?a=API_GenAddRecordForm&_fid_11=" & URLEncode ([Employee ID])& "&z=" & Rurl()

It doesn't matter if I change "11" to "2" whatever is select in the form roles section opens.

Can I specify the form to open and still have it open in Edit mode?

Thanks,

Brian
