Problem with input terminal, sub vi

[svt4cobra6]

Hi I added a terminal to a sub vi (trying to add an input terminal to accept a string input).  When I display the context help the terminal shows up with a pink wire but when I select the sub vi in the block diagram the new terminal does not show up so it is not possible to add the correct input.  the subvi is used in several places and the program will not run until I add the string input to each location the sub vi is used.

Thanks.

If the subVI looks greyed out, try right-click then Re-link to subVI.

that worked!  I have a subvi within a subvi and I need to make an enumeration input of the inner vi accessable when the outer subvi is used.  Any suggestions on how to set this up? thanks.

Open the outer subvi and go to the diagram. Right-click the desired connector of the Inner subvi and do a "create control". Add the new control to The connector pane of the outer subvi. Save outer subvi with a new name.
