I get this error code when trying to make a unit test, saying that the control name isn't unique. I can make it very unique and it still comes up. I deleted the control and remade it with the same result. Using LabVIEW 2009 SP1.
Could it be that the cluster that makes up your array element consists of two numerics that have no label at all, thus they are not unique since they both control names are an empty string?
