[Cartoweb-users] what this error relates to

Fri Mar 10 15:04:38 EST 2006

Hi All,
    I have wrote a small plugin which colors my map.The plugin colors the
map if i have 1 instead of -1 in the line 81 of the following code and
commented out line 108 with only single color.If i have got the following
code then i was getting the following error.
    Can anyone help me in solving this error.And also what changes i have to
make in order to solve this problem.
     One more thing if if i have 1 instead of -1 in the line 81   and
uncommentd line 108 then the map is either not displayed or some of the
polygons are displayed.
    Code and errors are as follows:

   Thanks In advance,

regards,
venu.
