You should consider that sometimes 0 are present?<br>

Hi Agus,<br>
<br>
The 'Generate Centroids' name is simply me reusing code, I'll fix this later...<br>
as for not being able to select anything, all I can think of is perhaps you don't<br>
have a valid polygon layer loaded, or if you do, perhaps it doesn't have any numeric fields?<br>
