Circular reference

Posted on by boarder

Hello, I have a problem here

If(IsEmpty(Filter(colBasket,Quantity= Quantity_input.Text))," ",LookUp(colBasket,Quantity = Quantity_input.Text).Quantity)

The problem is that is a Circular reference Between Properties. Quantity input is an input textbox and the field text Quantity is from my collection.

The idea is that I need to store every input that is added in my collection and than to show it.

Thank you!

Well, I have this scenario: I have a that Quantity input that will store my quantity of a product. After I set it up, I make a collection by pressing a button. (add to basket- that stores the name, value and quantity) After that I have a view basket area (in the same screen) that allows me to change the quantity if needed. I want to see the changes also in my main order menu
Now: In my menu order I added 12 pieces of gum. I pressed Add and that my collection is made with 12 pieces of gum. I go to my basket and change it to 8 pieces of gum. I go to order menu back and I still see 12 (even if in my collection there are 8 pieces)
Expected: In my menu order I added 12 pieces of gum. I pressed Add and that my collection is made with 12 pieces of gum. I go to my basket and change it to 8 pieces of gum. I go to order menu back and I will have 8 pieces of gum

Hi @boarder ,

If you want it to display the value of a field in a record, you need to set it to:

TheSpecificRecord.Quantity
