To be more specific, you will need to find the names of our input fields. They are something like in_xxx_xxx. You can run your project and use View Source of the rendered page to find these ids. Then you can edit the .jsp file for the transformation and include something like this:

<SCRIPT>
document.getElementById("in_12_34").tabIndex = 1;
document.getElementById("in_56_78").tabIndex = 2;
document.getElementById("in_90_12").tabIndex = 3;
</SCRIPT>

Then run it again.

Seaching in the HATS documentation I found this: User's and Administrator's Guide > Modifying a HATS project > Other > Client Settings. HATS Documentation Scroll down just a bit until you get to the section titled Enable automatic field advance. The following section titled Include host and non-host input fields is what struck me. Try selecting the box this section refers to and see if it fixes your problem.
