I have a school as a client and they have been looking for exactly what the "Member Homepages" option provides. When I installed it, I ran into several errors, but I know this module is still in development. Since it looks like it hasn't been worked on in a while I have two problems that I just can't figure out. And I am not a "trained" programmer by any means, so forgive any "dumb" questions
PROBLEM #1:
The images block always causes the page with that block on it to report this error:
Notice [PHP]: Undefined index: fieldid in file modules/homepages/class/blocktypes/image.php line 215
It might have something to do with me not adding any images to the block yet. But that function doesn't work either. When I go to the edit page for an image block the Image manager button doesn't do anything. When I put in a URL to an image in there, the page with the image block on it appears blank with no error.
Here is the code for that file:

?> PROBLEM #2:
It looks like none of the default xoopsform areas are working properly. None of the formatting, date/time, or "Add" buttons seem to do anything. I am not getting any PHP errors though.
Thanks for your help!
