case structure undirected tunnel error

The Labview Basics solutions has a "Determine Warnings Case Structure.vi" example which has embedded "if/then" case structures. However, when I attempt to duplicate this in version 8.2, which is what I have, an error occurs when I connect a string constant in the innermost case structure to the string indicator outside all the case structures. The error "undirected tunnel" message states that the tunnel cannot tell which is an input or an output and that I should connect to exactly one input to determine data flow direction. There is no problem tunneling through only one case structure border, but it will not allow going through two case structures (and presumably more). Anybody know about this?

Problem resolved. I had moved previously used controls to a different part of the structure box; though they did not appear to still be connected to the outputs, apparently they were. When I added a new output indicator, it connected straight away. Thanks.

Hai,

Yes when more than two controls are connected to a single indicator that error arises. Its nice to c ur immediate response to your answer as well.

Hai,

Sorry for the above post. Its actually if more than one control is connected to a indicator outside the loop, then the error message "undirected ...." will appear.

Thanks,
