Hi Justin -
You can do this with a valueexpression in the column like this.
displayname=Hours by Job Role
listdelimiter=<br>
listmethod=nested(hours).lists
textmode=true
type=iterate
valueexpression=CONCAT({assignedTo}.{name}," (",{role}.{name},") - ",{workRequired}/60,IF({workRequired}/60>ABS(1)," Hours"," Hour"))
valueformat=HTML
This may not be exactly correct depending on what 'type' of report you're creating.
Hope this helps,
Teale
