SubVI is missing

LabVIEW cannot find the subVI in the file system. The subVI file has been deleted, moved, or renamed. When LabVIEW cannot find the subVI, the subVI is dimmed, and its icon contains a question mark.

If the subVI has been deleted, you need to delete the icon for the missing subVI and create a new subVI to replace the missing one.

If the subVI has been moved or renamed, right-click the missing subVI and select Replace from the shortcut menu to display the Functions palette. Click the Select a VI palette icon on the Functions palette and navigate to the proper subVI.

When you replace the subVI with one that has a matching connector pane, the subVI appears darker, and the wires are not broken.
