Another query please.

I wrote the following code to test the use of roi.contains(x,y) from within a macro. I have code before it which loads an image, thresholds, masks, outlines and opens roimanager. I also checked to see that the roi list is populated and the image displays the rois and a selection.

When I run the code

 index          =getNumber("Enter number of ROI", 0);
   index        = index--;
   roiManager("select", index);
   x            =getNumber("Cursor X", 0);
   y            =getNumber("Cursor Y", 0);
   roi_flag     =eval("script", "roi.contains(x, y);");
   if (roi_flag==true) print("roi flag=Inside\n");
   else print("roi flag=Outside\n");

I get this output in my Log.

ReferenceError: "roi" is not defined. (<Unknown source>#1) in <Unknown source> at line number 1

Although it references line number 1 it is not line number 1 of my program.What am I doing wrong?

Thanks.
