I have a problem with passing a cluster of references to a subvi. I want to create a logfile containing a list of all the values within my main program. This consists of three clusters, and 13 arrays. The clusters are 12 values each. The arrays are a mixture of 32 or 48 element arrays. I have created a reference to each of the indicators, and used "Bundle by Name". (In fact, what I have to do, was "Bundle", and create a control to that Cluster. I then turned the control into a typedef, and replaced the "Bundle" with "Bundle By Name". If this is wrong, please tell me how else I can do this!) So now I have a typedef ('InputRefs') which can be used as input to the WriteLogFile.vi. The error I have is: Front Panel Terminal 'InputRefs': Hidden front panel control has undefined type (one for each element of the arrays.) If I open the typedef, I see the array icons within the Cluster have a small red 'x' within them. What's going on, and how do I fix this?

I'm going to try replacing my subvis with the Replace Array method, and see what happens. Thanks for your help so far.
