spaceLocator -n temp01_r_armFkA01_loc;
spaceLocator -n temp01_r_armFkA02_loc;
float $locWp1[2]=`getAttr temp01_r_armFkA01_locShape.worldPosition[0]`;
float $locWp2[2]=`getAttr temp01_r_armFkA02_locShape.worldPosition[0]`;
distanceDimension -sp $locWp1 -ep $locWp2;

// Error: Error while parsing arguments. //

I get this error on the distanceDimension line - probably because of how I am trying to pass the coordinates to the start and end point arguments. Can someone tell me how I should do it.

Thanks,
Ron

Edit:
Even this,

$t1="-sp 0 0 0";
distanceDimension $t1 -ep 0 0 0;

does not work. I am just not getting it.
