You can make the cluster by hand, but a shortcut is to right click on a wire that is already the cluster type. Create a Control using the popup menu. Copy the control and paste it on the global panel.

Note that global VIs can have multiple controls on them, and you then select the control that you want from the global.

If you are still having issues, can you describe what error, or what things look like when you find yourself stuck.
