Are you sure that is exactly the code that is giving you the error. I can't see how that exact code could possibly give that error, assuming you typed in the 2 literally rather than acquiring it as the result of some process.
The only other thing that comes to mind is if you have overwritten the size function with a variable.
What does
which size
return?
