Matthew Kim,
Show us at least the error message.
If you don't want to also show us the code,
I recommend diagnosing the error by
printing some debug info in your process_msg function:
process_msg: func [var1 var2][
?? var1
?? var2
...
]
Run the program again to see the values of var1
and var2.
Then you can play around with foreach in the
console, using the values for var1 and var2 that
you saw.
