NewbieQ: Redisplaying Categorized Comments

Greetings, As my first web app with Rails I am creating an HR Tracking program. There are employee 'records' that can have 'comments' added to each record. I also assign each comment a category such as 'general note', 'disciplinary action', or 'job changes' which I've set in my Comments table using the values either 0, 1, or 2.

I can create the comments fine, but difficulty I am having is seperating the comments into different areas of the employee record page based on the category. So, for example, if I want to add a comment like 'Employee was promoted to manager' and assign it a category of 'job changes', I would then want that comment to display in a list below the heading 'Job Changes' on that records 'show' page just above the comment form.

The best way I can think of is doing something like: <% if comment_type = 1 %> <% for comment in @record.comments %>   <% end %>   <% end %>   but I can't seem to get the syntax correct. Can anyone assist? Below is my code and layout.
