Text Formatting ⇒ Changing numbering of subsections

[Fryems]

Hello

I am having trouble creating a command to change the subsection numbering type. I.e Roman, alph etc

I am using xkeyval, and the problem exists within one of my keys. The command works for the ordinary section, yet refuses to with subsection.

\define@key{secch}{num}{\renewcommand \thesection{#1{section}}}
good version....................also works on this command:
\secch[font=ptm, count=3, num=\Roman]

\define@key(ssech){num}{\renewcommand\thesubsection{#1{subsection}}}
bad version.......................

Thankyou.

Duncan

P.S

Any help would be appreciated
