CRM Not allowing selection of reason codes

When we go to the task tab of a quote it will not allow us to select
complete, Win/Lose/Next or a reason code of though the task set has
the "Win allowed" and "Lose allowed" boxes checked for the task.

We are just starting to use CRM and feel that we may have missed
something in the setup.

If anyone has any ideas what we are doing wrong please let me know.

Thanks,
Wendy
