Solution Import Failure

Hi,

I am trying to deploy an managed solution onto my UAT server. Its failing with :-

The dependent component Attribute (Id=captureproposalfeedback) does not exist. Failure trying to associate it with Workflow (Id=53c2cf23-bd0b-4685-8511-87b5cb2ff4ac) as a dependency. Missing dependency lookup type = AttributeNameLookup.

I have checked the server and the field captureproposalfeedback on the Opportunity form isn't there but its a standard Microsoft field

Any ideas?

Thanks

Rhoddy
