I am having a hard time getting what was provided to work. I first had these in two separate while loops (one from a subvi, other from this vi) which when I went through the breakdown, it went straight to the first while loop again. So, I merged them into 1 while loop. Now I cannot seem to get the property nodes to want to work for me. 

Error:

small icon is just an example. My goal is to be able to use this with any size.

You didn't wire any reference into that property node.

If the graph you are interested in is in that VI, then you need to right click, pick Link To and drill down until you find the indicator whose property node you want to change.  This is known as an implicit property node.

Otherwise you need to find that indicator, right click and pick create reference, and wire that reference to the top left corner.  This is an explicit property node.  You only tend to use them if you might need to vary which indicator you are working with, or it is in another VI and you pass a reference to it from the other VI.

That fixed my issue, thank you!
