Dear Hildaa,

Use the debugger:
dbstop if error
Then run your program until is stops in the failing line.
Not inspect the values, which are used for reshaping in the command line. Any non-positive or non-integer values?
ROUND, CEIL, FLOOR, FIX create integer values.

Please post error messages together with the corresponding line of code. Otherwise we cannot guess, what the problem might be.

Good luck, Jan
