Need help making a cost estimator

I want to when i press a button "Add" (Lägg till) it will add the value in the box to the left (7) to a value which will then be presented in the text input on the top (Summa [TEXT INPUT] kr). How do i do this? I will add more products to the list which will then also be added in the same way. But what code on the button do i need to put in?

Also I will need a button to reset the value. Is this possible?

Re: Need help making a cost estimator

You can use a variable that represents the default value of that text input, which you can initialize to 0 (such as on the screen's OnVisible property) - and you can also use a button to set that value back to zero, resetting the value.

Screen.OnVisible: UpdateContext({ value: 0 })
SummaTextInput.Default: value
ResetButton.OnSelect: UpdateContext({ value: 0 })

On the list of items, I'm assuming you have them in a gallery. If the value (in krona) is represented by the column 'Value', then you can have this formula in the Lägg till button:

LaggTillButton.OnSelect: UpdateContext({ value: value + ThisItem.Value })

That will update the 'value' variable, and its value will be reflected on the text input.
