Why not use a progress bar?

>I'm not sure if this is possible, so I would like some advice. The best example of what I'm trying to do is found mostly on websites. Currenlty I have a form with a pageframe. The pageframe has about 12 tabs. I currently have the tabs hidden, and simply use a "Next" and "Previous" button at the bottom of my form to navigate between the tabs. The tabs represent a step-by-step process, they are hidden out of sight by positioning them outside the boundry of my form. I want to place some sort of class object at the bottom of my form that uses a horizontal scroll bar. On that object I'm going to place a graphical representation of each tab from left to right. This will be "my" way of allowing a user to click on a step they already completed. It's also a way to see what step they are on.

>I've never tried to place a "form" on a "form" , I'm not sure if it's possible. I haven't done any research on this yet. I thought I would start by creating this post. In the meantime I will be trying to find a solution.
