Trouble at the configuration - Vote

I´ve installed gallery and now I always get this error:

[...]
$gallery->app->default["poll_type"] = "critique";
$gallery->app->default["poll_scale"] = "3";
$gallery->app->default["poll_hint"] = "Vote for this image";
$gallery->app->default["poll_show_results"] = "no";
$gallery->app->default["poll_num_results"] = "3";
$gallery->app->default["poll_orientation"] = "vertical";

// Error: In Vote words and values, for name A (row 1) value A should be a positive whole number

$gallery->app->default["slideshow_type"] = "ordered";
$gallery->app->default["slideshow_recursive"] = "no";
[...]

I´ve tried a few times to put in the right values but I always get this!
For example I put in:

Very Good 5
Average 3
Bad 1

Always the same..
