Good day

I am trying to add various fields on PowerAutomate (data that comes from a Microsoft Form), but keep getting the error:

Unable to process template language expressions in action 'SumAll' 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).

Here is my flow:

After I have Summed up everything, I need to calculate an Average:

Can you please advise me on the error I'm getting on "SumAll" above?

Thanks

Your last add statement (for mul7Turnaround) only has one parameter. Removing that add statement (and it's brackets) should fix the error.
