Generating dynamically named tags

Hi All

I'm writing a template for use with CGI:Application::Plugin::ValidateRM.
C::A::P::VRM expects every field that requires validation to have a matching
field  with an "err_" prefix (i.e  err_field_name).

My field names are dynamic, e.g.

<tmpl_loop name=application_parameters>
<input type="Text" name="<tmpl_var name=field_name>" value="<tmpl_var
name=field_value>
</tmpl_loop>

but I can't figure out the best way to specify the error field. Obviously 

<tmpl_var name=err_<tmpl_var name=parameter>> 

doesn't work

Any ideas appreciated

Thanks

Dan
