Issue passing boolean value into a page include

I am trying to pass a boolean value of true into a page include to be set as a condition on one of my models. 

I have tried 

ShowRP=true

ShowRP=TRUE

ShowRP={{TRUE}}

ShowRP={{true}

and have not had any success. Please help.

Dg O,

The first one (ShowRP=true) is the correct syntax.  This will work fine if you are creating a new record.  If you are loading a model, be aware that the condition may mean that the model returns no records.

Thanks,

Bill
