Bear with me as this might be a two-part question. Is there a way to find the sum of multiple numbers in a list of values? Here's my method for getting the values:
1. I have an apply to each that gets specific values from JSON data.
2. I used the concat function to put all the numbers together using Compose. It looks like it's putting quotes around the values, so maybe that's part of the problem and this needs to be converted to an array first.
Whether or not the quotes are inhibiting my ability to add the numbers together, I'm not aware of any method to add more than two numbers together in Flow. Does anyone know how this could be accomplished?

Hi @Tchurch
Your numbers are in string format
you would have to typecast it to int
example int("5")
In order to get some of your array of numbers (string format)
Create a variable of type integer called total and initialize it to 0
Create a variable of type integer called temp and initialize it to 0
run a for loop on your array of numbers
within for loop
Set variable temp to following expression

Rather than using Compsoe, try the following:
Please let me know if this works for you.
@RezaDorrani This worked perfectly, thank you so much! It took a little fiddling to figure out exactly how to implement it, but I finally got it to return the total of the numbers in the array (which had to be converted to integers first). Here's a screenshot of my final setup in case anyone needs to do this also.
Can you explain it more briefly by expanding the actions and what parameters have you passed on the set variable action for adding 2 numbers.
As if I do the same I'm facing error :
Invalid Template. Unable to process template language expressions in action 'Set variable' inputs at line '1' and column '2764': 'The template language function 'add' expects its first parameter to be an integer or a decimal number. The provided value is of type 'String'. Please see https://aka.ms/logicexpressions#add for usage details.'.
This error happens when you add two variables directly to the add function.
For example, if your initial variables are x1, x2
add('x1', 'x2') will return this error because notice the variables are passed as strings and add is expecting integer or decimal
The solution for this is:
add(variables('x1'), variables('x2')) - This will add the numbers correctly
However, if you have requirement of adding multiple numbers,
add(variables('x1'), variables('x2'), variables('x3')) will NOT work
You can do the sum of multiple variables using the add function nested loop
For example if you have to sum 5 variables, this will work
add(variables('x1'),add(variables('x2'),add(variables('x3'),add(variables('x4'),variables('x5')))))
@Hameed_Hussain - thank you so much for the nested add tip - I've been shaking my head at the increment method and going, there has to be a better way!
I am just trying do get the nested solution to work, my function is:
add(variables('YardValue'),add(variables('JobValue'),add(variables('PlantValue'),add(variables('LabourValue')))))
Which I believe is correct but I get the following error when I run the flow:
Unable to process template language expressions in action 'MultipleSum' inputs at line '1' and column '14480': 'The template language function 'add' expects two numeric parameters: the first summand as the first parameter and the seccond summand as the second parameter. The function was invoked with '1' parameter(s). Please see https://aka.ms/logicexpressions#add for usage details.'.
Any thoughts or guidance gratefully received

@emoncada brilliant, thanks for pointing that out...my tired eyes completely missed that.
That compose method is a great idea.
I was looking to do exactly this.
I'm adding multiple columns - same line in a spreadsheet and I use the compose to dynamically make the array of each line and then add each value to the sum variable in a loop like @RezaDorrani suggested.
Works great since I am only processing the data, the compose keeps it very minimal and de-cluttered.
Just a note, I was going to build a whole add(add(int( .. . formula to add the columns. It would have been a mess.
