Child table form based on parent's field value

You can make a button called View

var text FormOne =URLRoot() & "db/" & dbid() & "?a=dr&dfid=2&rid=" & [Record ID#];
var text FormTwo =URLRoot() & "db/" & dbid() & "?a=dr&dfid=10&rid=" & [Record ID#];

IF([My Checkbox]=true, $FormOne, $FormTwo)

Then you will probably need a duplicate of the field if you want to edit.  But change the dr to er. 

If you want to stop users to not use the native view and edit buttons, then you put these on the report and deselect the report configuration checkboxes to Allow View and Allow Edit.
