How do I add workflows on a form?

It sounds like you are looking for an approval workflow - good news is that these are built into sharepoint libraries and just need to be onfigured. In other words you shouldn't need to use sharepoint designer unless you want to add complexity over and above what is offered.
The MS link below tells you everything you need to know about approval workflows in SP.

In a nutshell, add 1 or more people to the "approvers" permission group for the site in question.
Then turn on approval in the library settings.
When a person wants to publish a document an approval request will be sent to the people in the approvers group.
They can then approve, decline or send the request back with comments.
You can set it so that only 1 of the approvers needs to appprove or all of the approvers approve before the document reaches the published state.

Hi and thanks for your reply.

One question I have is about the approver. The approver will be one per step but not always the same person. The originator will select a supervisor from a drop-down and that will be the approver for that specific form. Then the supervisor will select a director from a drop-down and that will be the approver for that step. Is that possible to do?

Thanks!

Dear hackman122,

Your scenario can't be done using the out-of the box features in document library and approval workflow.
Let us start with your scenario roles, you have the bellow roles:
1- Originator.
2- Supervisor.
3- Director.

Now questions will popup to your mind, how to define the Supervisor of Originator? How to define the Director of Supervisor ?

You suggested drop down list which can solve your problem but not that easy, because you need to have the list of supervisors and directors as well, and from business perspective this is not good solution because originator might select wrong supervisor by mistake (it depends on how many supervisors in your targeted organization). Same for supervisor when selecting Director.

If your organization chart like this :
Staff (Originator) > Supervisor > Director
Then you can automatically assign the approval to the right person based on active directory, you get the direct manager of current logged in user using out-of the box action in SharePoint 2010 workflow.

But in all cases, you need to play with info path and SharePoint Designer as well.

Good Luck

I am still trying to set the workflows for my form and this is what I get:

I made the workflow as simple as possible just to test but it still doesn’t work.

Help please!

Thanks
