MWA - Accept any Task gets 'Invalid Value'

Hi,

Please see upload.

I am new to WMS module... I trying to perform an simple outbound test.

Created an Sales Order and performed the Pick Release

Swtich to MWA using Telnet

select 5 Tasks, 1 Directed Tasks, 1 Interleaved Tasks, 2 Accept any Tasks
Once I arrived at the screen 'Load (Inv Org)'
Confirm the Subinventory
Confirm the Loc and press 'Enter'
System prompt 'Invalid Value'... you can see on the last page

What setup/steps  have I missed??

Any help
