CMS Made Simple Forums

Hello, i would like to know if it is possible to use comments and FrontEndUserListing?
I would probably call the coments module in the FEU Listing template like this:
{cms_module module='comments' modulename='FrontEndUserListing' pageid=$entry->id}

The "Add comment" box appears and i can visually put the coment. BUT it doesnt get stored in the database or so.

I guess it has to do with  pageid=$entry->id. Maybe it should be something like  pageid=$entry->userid or so?

Any suggestions on this?

I am using
CMS MS 1.2.3
Comments v1.8.2
FronEndUserListing v0.4-beta

Thanks for your help.
