add() expression only allowing 2 parameters

[arvidb]

So, I am using Flow to load a Microsoft Forms response to a JSON file in Azure Blob Storage. All is working well. However, my form consists of tickbox questions that translate to numeric values that I want to add up.

The add() expression only allows for 2 paramaters while I have up to 8 paramaters (question scores) I would like to add up at once. The only solution I have found so far is to keep nesting add() expressions to allow for more than 2 parameters to be added at once.

Is there another workaround for this? If not, why is there no sum() expression in addition to add() that allows for more than 2 paramaters to be added?

HI @arvidb 

The add() expression just allows two inputs as you have marked. Instead of nesting many add() functions, i would suggest you to use arrays and increment array variable. Please have a look at the screenshot below: 

Hope This Helps!

Thanks for your response. This wasn't the exact solution I needed but it pointed me in the right direction so I accepted your answer as a solution.

My solution is as follows:

I initialize a variable set to 0, use an apply to each with an increment variable task for each separate form question with a corresponding value I want to add using int(<form-question-reference>).

The initialized variable now contains the sum off all increment variables added up.
