Problems with get transaction data/process

Hi guys, I’m having trouble storing values ​​inside the process.

I am working with a queue, it works well within the sequence, it gets the values ​​well to the invoke process, but when it removes another item from the queue it enters with the values ​​at 0. I have no default assignment.

I need to sum values, so I have to store the value.

I can’t solve it, since when it returns from get transaction data the argument is reset.

Thank you so much!

I work with reframework

You’re trying to sum up all the values returned from the queue items (one by one as it is returned)?
