Strange shift register initialization

[aputman]

The code in the Z Value event executes only when the Z-value changes.  So what is it changing to?  Is it different than the initial value?  That is the variable you should be observing.

Oh yes!

And all that to do something only with 10 controls...

Vi for equation with 5 parameters and 3 variables does not use clusters.

Maximum 2 local variables are required - if you save last parameters into file

I've run your code and don't see any issue with values not matching during initialization. I think your problem here has something to do with your equation not acting the way you expect, or maybe the Signal Value not acting the way you expect.

Either way, you're had a lot of talented LabVIEW developers trying to help you in this thread, so I'm not sure why a solution hasn't been found. I would suggest simplifying this VI so that you can make it easier to pinpoint your issue.
