Sorry, I am a little desperate. But, this is my only line that includes _TessaractScreenCapture() func _TesseractScreenCapture($get_last_capture = 0, $delimiter = "", $cleanup = 1, $scale = 2, $left_indent = 0, $top_indent = 0, $right_indent = 0, $bottom_indent = 0, $show_capture = 0) What is UDF? Undefined?
