Assignment 2 Dispatcher -GetTransactionData problem

i started with the second part of level 3 assignment - the YearlyReport.
The first problem is, the dispatcher part doesen’t work faultless. I see in the debug mode, that the init process with login(credential) and navigate to workItems and the process.xaml run good, no errors. But I think, it is a wrong way in the GetTransactionData.xaml. After login the first work item page is displayed, but the next step = next page is not displayed and therefore no items for the queue.
If i start the process.xaml standalone, the queues would be uploaded in the Orchestrator.
Can anyone check my xaml file please. What is wrong?GetTransactionData.xaml (13.1 KB)

ok, solved. I guess, it was a wrong selector.
