InfoPath Web Part sends blank value to List view WebPart


I would like to use a value (in a dropdown) from an Infopath web part (list form) to send a filter value to list view webpart. I have added a button to send data to webpart, I’ve also tried included this rule on the drop down. I feel like I’ve tried all the settings and such, but the Infopath webpart always sends “empty” value to the list view webpart. It doesn’t want to send the value in my dropdown, just send empty every time. I have send first row of data unchecked, and send data when page loads is also unchecked. Is this even possible? Or am I missing something?
Thanks
