Posted on by AB21

Objective: I have a form that functions as an order sheet, with data transferred to an Excel sheet. In the Excel sheet, I maintain a list of items and their respective prices in a 'Menu Costs' sheet. My aim is to create a formula or modify a Power Automate workflow to calculate the total cost for a list of items extracted from Power Automate. These items are enclosed within square brackets and separated by commas when multiple items are selected.

Menu Cost:

Current Formula for a Single Item: =VLOOKUP(E2,'Menu Costs'!A:B,2,FALSE)*C2

Sheet 1:

Form question for food options:

Question: Can Power Automate be utilized to calculate the cost for multiple items within the 'Food Options' column and accumulate them into the 'Total Cost' column?

Hi @AB21 ,

Here's a working solution from another question I answered last week; works good!

Initialize two variables as shown below.

Here's the expression for temp1 above:

add(variables('sumtotal'),int(item()))

This works well and will loop through your array and add up the numbers. I like this option very much and is my current go-to model.
