Workflow rule not working

Workflow rule not working

Hi all,

I am trying to create a workflow for time entry, but I don't have the options. This is what I have done.
Workflow->Create Rule->Module->Time Entry
Execute->Create
Criteria ->Description->Contains->Reply
Action-> I only have "Custom Function"

I need to update the "Time Entry Type" field with "Email Reply" which is one of the options

Any help is appreciated.
