WorkFlow type in dropdown property of designs of the listpage is not available.

Hello

 I am creating a workflow to have someone approve when prospects are made customers. 

Could someone please tell me why is query important to have a workflow ? I didnt create a new query as smmBusinessRelations_NoFilter already exists and I am using it.

Also, when I chose to add workflow to the smmBusinessRelationsListPage 

I have to change 3 properties in the design menu

Workflow Enabled            :        Yes

WorkflowDatasource        :        smmBusRelTable

WorkflowType                  :        (I Want to chose my workflow type here)

But sadly the drop down doesnt show anything ?

I have checked my workflowtype properties and in its DocumentMenuItem I have chosen smmBusRelTable , I can also choose smmBusinessRelationsListPage not really sure if that changes anything.

Thanks
