Hello everyone!

So i have a main screen where i use two blocks: A 'Header' block and a 'Content' block. Inside the content block, it uses another block as a list item. 

In this 'last layer' list item block, there is a value that is saved using the OnChange event action. And, considering it's in a list, there's an array of values. I add up all these values present in the list into a Total Value variable. And i want to use this Total Value in the Header block.

Here's a way to visualize it better in layers:

So, i use an Event in the ListItemBlock to send TotalValue to ContentBlock, and then, in the EventHandler in Content Block, i save the value that is brought by the event in a local variable, and i I call a NEW Event to pass this value (TotalValue) up to the Screen. 

In Screen i also use the handler save the value from the Event in a local variable. And pass this value to Header Block as an input parameter.

My problem is: Up to Content block, the TotalValue is sent correctly. But when i use the second Event (SendTotal), it is passed as 0 everytime. Am i doing something wrong? How can i achieve this 'double layer event' usage?

I hope i was clear. 

Thank you.
