python - Django : multi variables in urls.py not working -

i'm trying construct url 2 variables in template, yet same error message. i'm quite new djang , drives me quite nuts, need :)

exception type: noreversematch exception value: reverse 'skill_update' arguments '()' , keyword arguments '{u'instancepk': 1, u'skillpk': 15}' not found. 1 pattern(s)  tried: [u'persomaker/skill/update/(?p<skillpk>[0-9]+)$/(?p<instancepk>[0-9]+)$'] 

template :

{% url 'persomaker:skill_update' skillpk=item.pk instancepk=instance.pk %} 

view.py :

def skill_update(request,skillpk,instancepk):     form = skillcreateform(request.post)     user = user.objects.get (id = request.user.id)     instance = character.objects.get (id = instancepk)     if form.is_valid():         form.save()         return redirect('persomaker:skill_list', instance.id)     else:         skill = skill.objects.get(id=pk)         form = skillcreateform(initial={'character':instance})         form.fields['skill'].widget = hiddeninput()         form.fields['level'].queryset = range(0,7)         form.fields['character'].widget = hiddeninput()     return render(request, 'character/create_skill.html',     {'instance':instance,     'form': form,}) 

url.py :

url(r'^skill/update/(?p<skillpk>[0-9]+)$/(?p<instancepk>[0-9]+)$', views.skill_update, name='skill_update'), 

you have $ in middle of pattern regex. that's terminating character; nothing after ever match. remove 1 in middle.
