Can variables add the subtotals of a table?

Hi @Ryan_Feeley

I don’t know if this the most elegant method but I’d make two variables per fruits

• one for quantity,
• and one for price
  (the one for price is more for comfort, so if you change the price, you’ll just have to change its value from local variables rather than having to go through every interaction to change it.

+ an additionnal variable for the Total.
Note that #total has to be calculated everytime you click on a button, at the last step of the interaction

i.e: when (+) for Apples is clicked you assign the new value to #apple_quantity and then add the price to total: #total = #total + #apple_price

Let me know if it helped

Thanks! If I am understanding correctly, this gets me to the subtotal, but not the entire total. I think I need three variables per fruit… for example:

#appleprice × #applequantity = #appletotal and then an #ordertotal for the entire order which would be the sum of #appletotal, #orangetotal, etc.

I thought I could apply the prototype interactions to the components, but I guess not 😦

Unless there is a way to do it with fewer variables?

Yeah 3 will do. Sorry, I forgot to take the subtotal into account

You can make interaction directly on the component. You’ll have to change the fruit variable for every instance tho but it’s definitely possible to do so

There maybe is but I’m not aware of it. While working with variables for a prototype I always tend to have as much variable as needed. If I want to change something later I want it to be easy and fast. I mean, I’m their to design not to develop a bulletproof solution.
