Custom SharePoint Form that displays data from another List

Question

I have a SharePoint task list. Each task in the task list is for a Client, and there is a drop-down on the task entry form to select the client. The drop down is populated from a Clients list.

Each client has a tier. Tier is a field in the Client list.

What I want to do, is when a Client is selected in a New/Edit/View form from within sharepoint, I want the Tier to display.

I've created a Custom List Form in SharePoint designer, added a row to the form for the tier, but can't figure out how to populate the tier. I don't want it to be a form field, just to display for FYI purposes.

Any help would be appreciated.

You could use jQuery to do this. There is a community-driven jQuery Library for SharePoint. The SPCascadeDropdowns function is probably what you need.
