I have a lisp that cuts cross section profiles of polylines. Once in a while I get this error, and I have no idea why. I do everything the same as normal, but it happens now and again and I can't find any resolution, even if I draw another polyline right next to the one that gives me the error, and I get the same error on that one, even if I draw the line starting from both ends.
Here is the lsp:

Here is the error:

Command: qp
Please enter the layer name of the contours: btw-xsec
Select the Horizontal alignment:
Enter the vertical exaggeration <1>: 1
error: bad argument type: numberp: nil; error: An error has occurred inside the
*error* functionAutoCAD variable setting rejected: "PICKBOX" nil
{code}
Any help or ideas whould be appreciated. If you have a lisp that cuts cross section profiles that is simple to use, that would help also.
Thanks
