If you mean that there's no way to wire into it, or out of it, then here's a possible fix ...

Open the problem VI, on it's front-panel, right click the VI's icon in the upper right and select "Show Terminals". If none of the little squares are colored in, then there are no terminals (they disappear if you delete the original source control/indicator).

To connect something to an output/input "pipe", then simply hover over the little square that you want it to come in/out, click it, then click on the item you want to link to it.

Hope that helps.
