The syntax I sent was incorrect (both times), as you discovered. I think the syntax you tried is right, but I think the “d” in data should be lower case. As Bill points out, I would also try making your parameter name different between the Master PI and Child PI. Maybe use &cid={{$Model.accountQFR.data.0.Id}} and change the model condition on your child PI to match the cid parameter name. I posted this last night, but I don’t see it on here.
