You have a variable named "plot" in your script that is overriding the function 
named plot. What looks to you like a function call is actually indexing into 
the plot variable. That's why the error is reported as coming from your script 
and not from inside the plot function. Try renaming the variable plot in your 
for loop and you should get better results.

Thank you!!! That was it, and I was definitely never going to figure that out. 
I only program in strongly typed languages that can't swap a function for a 
variable.
