InfoPath Dev

I have an InfoPath 2010 form. I am creating a workflow and need to query/pull information from the InfoPath form. I cannot find anywhere to achieve this.

 What I am wanting to do is within a loop determining the stage (set within InfoPath) of the form and set the appropriate workflow state. Based on the stage I have the email address of the next person to approve (2-10 people based on the options within the form).

 Can anyone provide information, links, etc.?

I assume you're using InfoPath and SharePoint 2010. I assume a button or something updates a field called Form Stage.

Publish your InfoPath form and promote your required columns i.e. Form Stage. If you haven't already create an "Admin view", so that if required you can change/alter the Form Stage field. - Great for testing/troubleshoot. See point below.

Natively you can't "loop" within a SP workflow. You can to an extent get around this with an Else If and Wait statement.

In your workflow you would just use Wait Until X equals X. Then email X.

You might need to promote the columns of "people" you want emailed or use SharePoint groups.
