Hi Igor, 

You can supply more parameters than the defined function as long as you
explicitly set the rest of the parameters (so when the function with 3
parameters is called it'll supply the other parameters too to the
"receiving" function).  

I think Peter has the answer with his reply, I am using too many parameters
(there is a limit it seems).  I'll try to bunch them together in a structure
perhaps.

Thanks for your help
All the best,
Ash
