Case Structure

[Trinity32244]

Getting back into labview after a long break.  Have a 2D array that just need to index with buttons to show a particular pump info.  This can't be the most efficient way to do this and not sure why the case structure is giving an error?

The Last Shall Be First.  Did you click the Broken Arrow and look at the list of Errors?  Do you not understand "Case Structure:  No case for some selector values"?

Your Selector is a Boolean.  It has two Values.  How many values are in your Case Structure?  [Hint -- the answer is not 2].  Hence an error.  On the other hand, you, at least, are consistent -- all of your Case Structures have the same Error.

LabVIEW Is Not Matlab.  LabVIEW is not C (or C++).  There are tutorials shown on the first page of the Forum.

I cannot figure out what you are trying to do -- it makes no sense to me.  Maybe spend a little less time developing a fancy Front Panel (with all of the Labels hidden so we have to "hunt around in the dark" to find the variables you are using) and more time with, maybe, a 2D array of integers and work out the logic that way.

BOW_Selected should not be a Float -- it is used as an index to an array.  See the coercion dots?  [Those are the little red dots where the orange wire goes into an input that is expecting "something else"].  They are a "hint" that something might be wrong, or at least "illogical".

Thank you Bob.  I added the false case and the error went away.  No other programming language I have used requires that so didn't make sense to me.  The code was meant to just simply be a way to scroll through the array with the first, previous, next and last buttons.  Just seemed like a lot work to implement and figured there was a much more efficient way to do this that I wasn't thinking of.
