Thanks, it wouldn't let me drag and drop because I have an earlier version of LabView. Would you be able to just post the .vi so I can work with that?
If you have an "earlier version", you need to tell us what version that is. Else a VI will no help you either unless we guess right. (Seems to be 2016 from your first post.) Also note the correct letter case of the word LabVIEW.
Well there's your problem...
You need to use Queues, Notifiers, or Channel Wires to pass data between While Loops.
In your case I suggest you study the Producer/Consumer architecture, as that's pretty much what you are trying to do from the looks of it.
Here is the vi posted by Sebastian.Weber saved for LabVIEW 2016.
