Filtering noise from a load cell

$

*About half way down my Main Program I have my scales that I'm talking about.

 

I have a scale that uses a load cell for measurement.  It outputs a signal in mV that I then use a formula node to convert the signal into pounds.  I've gotten all of that, but I can't figure out how to filter the noise.  I've done a lot of research and from what I've seen, I'm assuming a butterworth filter would be my best bet (I think).  The problem is I'm not sure how to convert my scalar output from the formula node into the 1D array of the input to the filter.  Am I correct in using the Butterworth Filter?  If so, how do I connect it properly?

 

I also have two other ideas I've tried.  I have "Sample Compression" and "Filter", from the Express tab in Functions, on my main VI as well.  I'm not sure if either of these two ideas might work better.
