And here is my template again

<perch:content id="jobID" type="text" label="Job ID" help="Leave empty, only used by BroadBean" suppress="true" />
<perch:content id="jobRef" type="text" label="Job Reference" help="Reference as displayed on website" suppress="true" />

    </perch:after>
</perch:categories>

    </ul>
    </perch:after>
</perch:categories>

<perch:related id="consultant" collection="Team Members" label="Assign A Consultant">

<div class="row job-list-item">

                </p>

            </p>            

                <perch:categories id="jobSector">
                        <span style="display:block"><perch:category id="catTitle" type="text" /></span>

                <perch:categories id="jobRegion">
                        <span style="display:block"><perch:category id="catTitle" type="text" /></span>
                </perch:categories>

            <a href="" class="btn btn-primary">Read more</a>
        </div>
    </div>
</div>

and the related field (Team Member) template

<perch:content id="teamMemberName" type="text" label="Name" required="true" suppress="true" />
<perch:content id="teamMemberSlug" for="teamMemberName" type="slug" label="Slug" editable="true" indelible="true" suppress="true" help="Do not change this unless you know what you're doing!"/>
<perch:categories id="sectors" label="Assign to sector" set="sectors" display-as="checkboxes" />

<p><perch:content id="teamMemberName" type="text" /></p>
<img src="<perch:content type="image" id="teamMemberImage" label="Image" bucket="team" />" />

incredibly frustrating as I really need to be able to assign team members (consultants) to jobs and your video example using authors works like a charm! :-)

Am I missing any steps, do I need to have page / slug specified or something?

Many thanks
