How to access Sharepoint List Items using an ID

I am currently working on a nice table that displays the items in a list of "Tasks" on a dispForm page. Each Task is created and initially given a ProjectID depending on which project the task is for. The ProjectID is the actual ID given to the "project" when it is added to the list, therefore it is not actually a parameter in the list of projects while it is a parameter in the list of tasks.

I would like to know how to use the ProjectID parameter in the task list to link to the Project list and grab the ProjectName parameter so that I can display th开发者_开发知识库e Project Name in the table. Currently I can not get it to work.

All help is appreciated, Gale
