Hi Lino,

Can you show us the previous lines that show what col is equal to?

Hi Lino,

I noticed at least one of those fields contains special characters. If you don't include that column (or any other column with special characters) dose the code run fine? I wonder if the problem is the encoding in the text...

I do not think the problem is the encoding in the text, because the problem is column "SHAPE", bu I do not know why it cause.
