000608: Line <value> in file with contour values is wrong.
Description
The file containing contour value specifications can include the following:
Any line that starts with a nonnumeric value will be ignored and treated as a comment line.
A line with three values will be treated as base, contour interval, and indexed contour.
A line with four values will be from, to, by, and indexed contours.
A line with a single value will be an explicit contour value.
Solution
Correct the line and try again.
