I went into document library settings -> workflow settings -> approval
Created a parallel workflow with 3 approvers.
The fields of the doc lib are:
Name, Category (choice), Country (choice), Owner (Person)
Now after uploaded a document, it shows me a blank screen and didn't ask me to enter the remaining fields. This is the first problem.
I received the approval email which is good. But the document gets uploaded straight to the library without even anyone approving it yet. This is the second problem.
