The configuration dialog for this plugin will let you configure any combination of page count or word count. If you want both, then you need to first setup two custom columns (using Preferences->Add your own columns, or right-clicking on the library view headers). Both columns should be of column type "Integer".
Once you have done that, then going back into the Customize plugin dialog for this plugin should let you choose your columns from the dropdowns. Leave the relevant column blank in this dialog if you don't want to retrieve that particular value.
See the attached screenshots. If a column you have setup doesnt appear in the dropdown on the customize dialog for this plugin, it means you set it up with an incompatible column type. Delete the column and create it again.
And if your problem is somehting else (your posts have been very vague) then post a screenshot with some detail and we can try to help.
