Sorting RG using Search from another page

Hi All,
I’m trying to send data from search fields on one page to be used as sorting data for a RG on another page. I’m using the URL Parameters to accomplish this but it isn’t working.
I have a workflow navigating to the new page and sending URL parameters then in the RG I have a search for all of the types of data and sorted by “Get from page URL”.
However, the Debugger reveals that the information in the search boxes isn’t being sent and is reporting as empty.
Is there a better way to do this than URL or am I just making a mistake in the flow? Any help is appreciated. Here are some screenshots. Thank you in advance.
