Delete DRC mark

Hi Sir,

The skill code show the error as below:

But I only need 1 refdes & 1 error that  the error is the minimal airgap.

axlSetFindFilter( ?enabled '(noall drcs) ?onButtons '(drcs))
Markers = axlGetSelSet(axlAddSelectAll())
DRC2_Markers = setof( x1 Markers rexMatchp("Externally Determined Violation" x1~>name))
 (foreach x1 DRC2_Markers
  (foreach y1 remove(x1 DRC2_Markers)
   a = atof(flatten(x1~>actual))
   b = atof(flatten(y1~>actual))
    (if a > b then
     (if x1~>violations~>parent~>parent ~>refdes == y1~>violations~>parent~>parent ~>refdes then
      axlDeleteObject(x1)
     ))))

error message

=> E- *Error* mapcan: argument #2 should be a list (type template = "ul") - "1.42308 mm"
