Error message in Perl... Undefined xxx

[sjDelaney]

What causes this kind of error.  I assume it's coming from Perl.


Undefined subroutine &main::GetValue called at /Users/sjDelaney/Programming/Read CSV 05.pl line 83.

The error is indeed coming from Perl, it indicates the GetValue function has not been defined. It is probably meant to call the exiftool function, but it looks like the code is referring to it incorrectly. Have a look at line 83 of the mentioned file and you should get a hint as to what is wrong.

You're attempting to call GetValue() without an ExifTool object.  See the examples in the API documentation.
