a printing vi gave error,what's the meaning of "refmum invalid"

[fenny]

i modified my program which used to print out only 3 of my 9 graphs, now the program gave an error :code 1055, refnum invalid. can anybody help me to see what's wrong with my printing vi.

I don't think anything is wrong with it. I think that you are not passing in a reference correctly for one of your graph references. Once I cleaned it up a little, it looks like it should be working properly. Maybe you can run it with execution highlighting turned on to find out which refnum is invalid.

Hope that this helps!

thanks, you are right, the problem occurred after I INCREASED the connectors of the vi. two many connectors got mixed up
