Floating Pool - Adding new Devices

First all I'm new to the site however not totally new to VMWare just VMView. The original administrator for the our view environment setup a Floating Pool however I cannot figure how to add a device.

Usually when I go Pool>Inventory> Add I  search for the newly created workstation and add it to the pool, however with this pool I'm presented with a different with screen that states the following:

Enter Desktop Names

Enter names that will be used to create new virtual machines.

Each line must contain a unique desktop name. Optionally, for dedicated pools, a user name can be specified also. User names will be ignored for floating pools.

I attempted to add the new workstation it shows up in the pool then it disappears. 

Thanks,

Mike
