I'm trying to pass an array of fault counters (starting at zero and counting +1 every time a fault condition is met) to a subVi that may or maynot add to the indvidual elements and then passes out to a shift register. When the code runs the signal coming from the Main Vi outputs once the 2,0,0,0 array intot the subVI "shift register fault array" input, then goes grey (probe display). The "shift register fault array" in the subVI never sees the 2,0,0,0 array and remains greyed out. The build array correctly builds the current cycle fault elements but when added to the greyed "shift register fault array" the output becomes greyed 0s. I built a simply array adding VI to test if my property node call was causing the issue but the test program works correctly. Any ideas?

LabVIEW

Shift Register Fault Array in the picture 5Ch_Fault_SubVI_array_handling.jpg. Where is the terminal for that ? Where does it get its value?
