Visible/invisible property nodes

Hello,

My question is somewhat complicated...For my program I have Labview connected to a force plate through an invoke node. When the forces on the force plate reach a certain threshold I want Labview to display 1 of 10 different indicators on the front panel. I've designed my program so that a random number generator picks which indicator will be displayed. I created a case structure that has 10 different cases to make all other indicators invisible and to just show the one that was randomly selected.

The problem is that I only want Labview to display just one indicator. For some reason when I run the program Labview is constantly polling the force plate data, and it gives me mulitple indicators, even before the force plate reaches the desired threshold. I tried using a stacked sequence to make sure that the random number generator doesn't fire until the threshold is reached, but for some instances Labview will show 2 indicators on the front panel by flashing one quickly, then finishing on another.

Does anyone have any suggestions as to how to get Labview to only show me one indicator?

Thanks
