Hi there, so I'm not sure what you have already tried, so apologies if I am being too obvious.
1) I assume you are including the qvs in your load script e.g.
2) The SUB you have in the QVS is only used once in the file i.e. the QVS is not some massive library and you have the Sub name used twice for different purposes
If you are doing both the above then I don't know, can you give a basic example of qvw and qvs you can attach or alternatively I can do one showing you calling a SUB from a QVS working?
