Thanks Adrian!

I am trying to dislay an error message 'You are not allowed to submit to this category' for certain categories for users.

I tried this. (It is from my 'mint' templates) Not working.

<%category_template_form('set', 'include_error_page.html', '262')%>
<%category_template_form('set', 'include_error_page.html', '263')%>
<%category_template_form('set', 'include_error_page.html', '270')%>
<%set form = category_template_form($ID)%>
<%if form%>
<%form%>
<%else%>
<%include include_form.html%>
<%endif%>

What is wrng about it?

thanks.
