## How do I make a calculating conversion table in CDS/PowerApps?

Excuse me for the extremely novice level (I don't even know how to form the question quite right!):

I am converting an Excel spreadsheet I made into a PowerApps "recipe calculator" (using CDS), but don't know quite where to begin.

How I imagine the solution is two tables: Recipes and Base Ingredients. The recipe would be the unique name, ingredient1, ingredient2, ingredient3, (etc) with the values in percentages. The Base Ingredients would be Ingredient1, ingredientA, ingredientB, ingredientC, (etc)... again, with the values in percentages.

So, basically, "Ingredient1" is made up of 75% ingredientA, 25% ingredientB, "Ingredient2" is made up of 10% IngredientB and 90% IngredientC. The recipe "Unique123" is made up of 50% "Ingredient1" and 50% "Ingredient2". The calculator would return "IngredientA: 37.5%", , "IngredientB: 17.5%", and "IngredientC: 45%".

The actual calculator would be a dropdown that selects the recipe (displaying the name) and a list of the TOTAL amount (in percent) of the A-Z ingredients.

The issue I'm running into is how to link the two tables together to perform the calculation. In Excel, I just did the calculation in the field of the Base Ingredients.

## Re: How do I make a calculating conversion table in CDS/PowerApps?

Hi @Manorexia ,

1)I suggest you create 2 tables(Recipes and Base Ingredients)

table1: Base Ingredients( what is "Ingredient1","Ingredient2",... made up of)

The structure of the table is：

IngredientID(text)          A (floating point number)           B          C

Ingredient1                    0.75                                           0.25

Ingredient2                                                                       0.1         0.9

table2: Recipes( what is recipe "Unique123" made up of)

The structure of the table is：

recipeName     Ingredient1        Ingredient2

Unique123         0.5                      0.5

2)insert a drop down, a button, a datatable.

Set the drop down's Items: Recipes      Value:recipeName

Set the button's OnSelect:

`ClearCollect(test,{recipe:Dropdown2.Selected.recipeName,                  A:LookUp(Recipes,recipeName=Dropdown2.Selected.recipeName,Ingredient1)*                    LookUp('Base Ingredients',crb4c_ingredientid="Ingredient1",A)+                    LookUp(Recipes,recipeName=Dropdown2.Selected.recipeName,Ingredient2)*                    LookUp('Base Ingredients',crb4c_ingredientid="Ingredient2",A),                  B:LookUp(Recipes,recipeName=Dropdown2.Selected.recipeName,Ingredient1)*                    LookUp('Base Ingredients',crb4c_ingredientid="Ingredient1",B)+                    LookUp(Recipes,recipeName=Dropdown2.Selected.recipeName,Ingredient2)*                    LookUp('Base Ingredients',crb4c_ingredientid="Ingredient2",B),                  C:LookUp(Recipes,recipeName=Dropdown2.Selected.recipeName,Ingredient1)*                    LookUp('Base Ingredients',crb4c_ingredientid="Ingredient1",C)+                    LookUp(Recipes,recipeName=Dropdown2.Selected.recipeName,Ingredient2)*                    LookUp('Base Ingredients',crb4c_ingredientid="Ingredient2",C)                  }              )`

Set the datatable's Items: test
