Hi Having moved onto Maya LT and lost Python, I'm struggling with MEL. This seems really basic but I cannot work it out. I am creating a window with 4 check boxes and I want the 'Reset' button to set them all to be 0. Simple I thought. I continually get the 'Object's name is not unique' when attempting to set the checkBoxGrp object. I can happily query it though. Any help would be much appreciated. Thanks! { string $window = `window -widthHeight 450 150`; columnLayout -adjustableColumn true; checkBoxGrp -numberOfCheckBoxes 4 -labelArray4 "One" "Two" "Three" "Four" drawModeCheck; button -label "Reset" -command "funcclear" -bgc 0.8 0.0 0.0; button -label "Close" -command ("deleteUI -window " + $window); separator -height 10 -style "in"; setParent ..; showWindow $window; } global proc funcclear() { string $adVal = `checkBoxGrp -query -v1 drawModeCheck`; print $adVal; checkBoxGrp -va4 0 0 0 0 -ed 1 drawModeCheck; }
