I am trying to link in some information into a sub-VI that was already created. I am taking over an old VI and I need to link something into the sub-vi. Thanks
Can you edit the sub-vi? If so, simply add a control in the sub-vi which handles what you want to pass to it. Add the control in the connector pane of the sub-vi. You can then wire whatever you want to pass to the sub-vi from the calling vi. R
