Why does LabVIEW say the wires are broken?

I see one broken wire due to 2 sources.  Not sure what is happening inside of the FOR loop though.  Can you post your project (or at least a reduced version that shows the issue)?

On the left, you have wired 2 sources on the same tunnel/wire, so that's 1 broken wire.

In the For loop, you are trying to wire a "Red" object from the first subVI to the input of the "Green" subVI, so a "Green" object. If Red is not a descendant class of Green (or share a common ancestor), it is not permitted.

FInally, the output of the For loop, is a 1D array of "Green" objects, which is probably not the same data type as the input of the last subVI on the right (it's probably a "Green" object scalar).

Overall, you can use the "List Errors" dialog box (Ctrl+L) to debug your code, and make exhaustive use of the contextual help (Ctrl+H) to see what is going on when focusing a broken wire.
