Using a sub-vi to write the strings of a ring inside a cluster on the main VI.

[sefnotu]

I have an array of ring controls in a cluster on my main VI. Now I
want to use a Sub-VI to fill in the strings of the text ring from an
array. I tried refnums and property nodes and "to more specific
class". I can access the ring array but whatever string I write in
there doesn't show up. Can anybody please give me an example of how to
do this?  I am using LabVIEW 6.02

Thanks
