Do you have a question or were you just letting us know what hurdle you surmounted?

Please post complete code. Please post it between
** **[code]** **
and
** **[/code]** **

The error is clear, the function requires at least one more argument; I do not know what that argument is supposed to reflect.

Please post the full error message; it's truncated in the title so the function might even require a third argument.
