Nokia 3310 / 5510 LCD assistance without library

I'm using the 1.0.3 Arduino IDE. The error that is being generated when I try to use:

 void LCDString(char *characters);

"In function 'void loop()', error: too many arguments to function 'void LCDString(char*)'

I honestly have zero idea what any of the syntax for the LCDString means.

And, the code given, where does it go? I tried a few different ways, and either I get errors, or nothing is displayed on the on the LCD. Yes I checked the connections. I reverted back to the original code to make sure I didn't break anything.
