Drupal 7.x

hello,

I am using Drupal 7. I am trying to create a set of categories of the blog post. I created a new vocabulary called Categories. There two elements inside. After I try to add an existing field in Content types- Blog entry . But when i click on the dropmenu of name, it doesn't appear the vocabulary Categories, but it does tags (default vocabulary by drupal). How can I get my vocabulary Categories as field in blog posts?

There are more people with this issue in the comments: http://drupal.org/node/23405

I have searched long and hard on how to just do a simple form that will output processed results in the $content area. It is impossible.

For the sake of argument:
Lets pretend I have a form that asks for two numbers and I want to add them and display the sum in the $content area. How would I do this? Google gives me results to drupal5 solutions...can someone point me to an example or tutorial?

I've put together the first of several torrents to share the Drupalcon Chicago Videos.

The first round will be the high-resolution MP4 files. If there is feedback I can work on a torrent for the low-resolution MP4 versions.

First Installment:

Day 3 - 17.6 GB - http://c494208.r8.cf2.rackcdn.com/drupalcon_chicago_videos_day3.torrent

I recently uploaded my site from my localhost to a web server. However, I am getting the following error at http://www.sdeyservices.co.uk/ :

Notice: unserialize() [function.unserialize]: Error at offset 428 of 4956 bytes in views_db_object->load_row() (line 1794 of /websites/123reg/LinuxPackage22/sd/ey/se/sdeyservices.co.uk/public_html/sites/all/modules/views/includes/view.inc).

This error is related to the views module and doesn't occur on my localhost.

The two main issues I'm having are:

I created a page-front.tpl.php and for some reason my theme is still only using page.tpl.php

What i'm trying to do is create content that will only show up on the home-page (a block).

But I still want on the theming from page.tpl.php to show up but I want the page-front.tpl.php content to show up inside of the

div class="maincontent" area

Hello,

I am just getting started with drupal and got my head around the basic concepts.

Now I am trying to organize a numerous pages of information into a hierarchy, which is not really a problem since I can make use of the "parent" field when adding content. However, I am a bit confused about the seeming limitations of content editing. How can I cross link from within a content body to other nodes without referring to their number? Or is that the preferred method?
