I had the same issue. The problem is due to the Search Criteria values not posted to Clipboard Before or on click of submit button
There are 2 approches:
1. We need to post the Search criteria value to Clipboard immediately on entering using Post Value Action using Change event on the Text Box before clicking the Submit Button. (No refresh of section is required in this Scenerio)
2. Refresh the whole section on Clicking the Submit button (button Click>Action - This should be the first action for the button) so that the values will be automatically posted to the Clipboard and you do the next action getting the Result from RD.
