help with rotation script, spinning object

I am trying to use the basic rotation script llTargetOmega(<0,0,1>, 1, 2);. I noticed that when I insert the script into my object it rotates in a clockwise position. I am trying to make to gears that rotate in opposite directions so I would like one to rotate clockwise and one to rotate counterclockwise. Is there a way to modify this script to make the object rotate in an opposite manner. I am not sure if I am explaining myself well but basically i have two circles, and I want them to rotate toward one another. Any help would be appreciated. I am not sure if I may even need a different type of script but I can barely grasp the concept of scripting.

Invert the sign of the spinrate

llTargetOmega(<0,0,1>, -1, 2);
