Accessing color

Hi Dave

I tried to use a code you provided in one of the forum below in 17.2, i'm seeing errors 

E- *Error* defun: too few arguments (at least 3 expected, 2 given) - (DE_setLayerColour (layer colour))
E- *Error* load: error while loading file - "L:/ecad_proj/MCLLIB_ZMY12_172/cjj082_adwlib/codes/col.il" at line 1

Tried reomoving the ")", seeing the error below. Am I missing something. Please Advice.
