$Model merge syntax for model id not working on Windows

Missing the data property. {{$Model.modelname.data.0.Id}}

My bad…missed that while typing…on page we already have {{{$Model.modelname.data.0.Id}}} 

The format is already correct…

The skuid page that has this template opens fine on Mac but on Windows gives ‘Id value is not valid’ error for the included page.

Double mustache should work.

No it doesnt. Have tried that already

Can you paste the XML here?

Do you have the Id field selected in your model “App”?
