Adding multiple variables

Posted on by tcm213

I'm trying to nest the add expression in order to add three variables using the below formula: add(variables('Answer1'), add(variables('Answer2'), add(variables('Answer3'))))

I'm getting the following error message: Unable to process template language expressions in action 'Compose' inputs at line '0' and column '0': 'The template language function 'add' expects two numeric parameters: the first summand as the first parameter and the second summand as the second parameter. The function was invoked with '1' parameter(s).

Appreciate any help here!
