Module development and code questions

When I enable the category module I get a bunch of errors on the modules page. I have a table prefix for drupal, which is "drupal_" could that have anything to do with it? Or is it something else?

The error I get is:

I'm writing a new module, 'Image Set.' It works along with the image module and provides image sets similar to Flickr's. The advantage of this module over the image galleries that are provided by image is that you can alter the order of the images for display any way you like. According to what I've been reading here in the forums, people were searching for alternatives to image exactly because the display order couldn't be changed, so I'm writing a new module that allows just that.

I set it checked in the content type configuration. But it does not work.

Any workaround?

Thanks

I'm a bit new when it comes to PHP and Drupal, so please forgive me if this is a dumb question. I installed the audio module because I am making a site for my friend's techno band. However, the module says when I am adding a new page that my current PHP configuration limits uploads to 2 mb. My question is, is it possible to link the audio module to an MP3 already on my server uploaded through FTP? If not, is there a way to update my PHP configuration or a workaround to make myself able to upload files larger than 2mb? Thank you!

Is it possible to display my $tabs from my node.tpl.php file? It seems like right now that variable only works in my page.tpl.php file.

Any help would be appreciated.

Thanks!

I'm looking for a module that will display in a block on the left or right side and allow for the showing of additional information relating to a specific node. My main motivator for this is for a review, where the big review would appear as the main node and a handmade summary/overview would appear on the side block somewhere. Ideally, this would be editable from the node creation page, but I'd consider other options.

Just wondering if anything out there exists like this or whether I should pursue it myself. Thanks!
