Trouble calling the "showChannelsLayers" procedure

[Ignasius]

Hi, This question is in reference to the Mel script lessons in the bonus videos of Maya in Production Vol 4-Advanced Rigging. Specifically the last bit of the the last bonus lesson where a button to call up the Channel Box and Layer Editor is scripted. The command is as follows
-c "showChannelsLayers \"Channel Box / Layer Editor\"";

I get an arguments error...I tried everything to no avail. Eventually I just turned on "Echo all commands" in Mayas script editor, opened the channelbox, and then pasted the whole script into edit plus. But now when I run the procedure it initially toggles the channel/layers boxes
either on or off. I am using Maya 2008 and am wondering if the `showChannelsLayers "Channel Box / Layer Editor"` procedure call has changed since that tutorial was made?
Its working ok with script copied from Mayer UI button but I'd like for it not to toggle the channel box when I initially call the procedure.
Any advice at all would be greatly appreciated. Thank you.

I realize that this is way after the fact, but I've recently completed the tutorial in reference and ran into the same error. Here is a solution:

showChannelsLayers takes two arguments, first a string then an integer.
The tutorial calls showChannelsLayers with only one string argument which is "Channel Box / Layer Editor".

I replaced

"showChannelsLayers \"Channel Box / Layer Editor\"";
with
"showChannelsLayers \"Channel Box / Layer Editor\" 1":

Just put a space then 1 in between the two end quotes to fulfill the second argument that calls for an integer.
