error msg: Allowed workflows for this item

Created an itemtype. Created a Lifecycle Map for the itemtype. Created a Workflow Map and referenced in appropriate state of the Lifecycle Map. Trying to get to the point where I promote an item using the toolbar button to a specific state and trigger a workflow task for the approver to approve or reject. Instead, I get the following error: The workflow you are attempting to use is not one of the Allowed Workflows for this item. Suggestions?
