You may want to re-write that querystring as

?UID=11234&skin=modern

To re-state, you have two dtml methods, my_report and my_report_maker. 
The user calls my_report with arguments, specifies additional data in a
form and my_report_maker does the heavy lifting.

Use something like this for my_report:

-------

<dtml-if form_submitted>
    <dtml-var "my_report_maker(REQUEST)">
<dtml-else>
    <form method=post action=my_report>
    <input type=hidden name=form_submitted value=1>
    <input type=hidden name=UID value=<dtml-var UID>>
    <input type=hidden name=skin value=<dtml-var skin>>

    Other Variable A <input type=text name=other_a><BR>
    Other Variable B <input type=text name=other_b><BR>

    <input type=submit value="Create Report">
    </form>
</dtml-if>

-------

Now my_report_maker will have use of all required names and users will
be able to bookmark the intermediate step where they had two of the four
arguments defined.

HTH,
