Why does Django try the wrong url pattern?

Django tries the wrong url pattern but I can not find my mistake.

urls.py

     url(r'^message/(?P<advertisementid>(\d+))/$', chat_view, name="chat_view_with_toid"),
     url(r'^profile/(?P<userid>(\d+))/$', profile_view, name="profile"),
     url(r'^details/(?P<advertisementid>(\d+))/$', details_view, name='details'),

views.py

def details_view(request, advertisementid):
    advertisement_data = Advertisement.objects.get(id=advertisementid)
    return render(request, "details.html", {"advertisement_data": advertisement_data})

def profile_view(request, userid):
    advertisements = Advertisement.objects.filter(user__id=userid)
    return render(request, "profile.html", { 'advertisements': advertisements } )

details.html (from where I want to resolve to the users profile)

<a href="{% url 'profile' userid=advertisement_data.user.id %}" style="text-decoration:none;">
<input type="submit" class="details-btn-profile" value="Profile"></a>

    <a href="{% url 'chat_view_with_toid' advertisementid=advertisement_data.id %}" 
    style="text-decoration:none">
    <input type="submit" class="details-btn-contact" value="Kontakt"></a>

main.html

<a href="{% url 'details' advertisementid=advertisement.id %}">
<img src="{% static advertisement.image.url  %}" alt="Image"/></a>

When I click on button class="details-btn-profile" Django gives me this error:

Reverse for 'details' with no arguments not found. 1 pattern(s) tried: ['details/(?P(\d+))/$']

Why does it resolve to details ? Any ideas ?

Sorry for wasting your time, I found my mistake. On profile.html I had this HTML-Code:

<a href="{% url 'details' %}" class="announce-hedline"><h3>BMW 320i Limousine</h3></a>

So "{% url 'details' %}" can not be resolved because of missing the advertisementid which it needs to be resolved.

I searched for mistakes in the wrong place.

Thank you all for your help !

when you click the button you send form where action wrong may be empty attr action something like it:

<form action="">

you need set it:

<form action="{% url 'profile' userid=advertisement_data.user.id %}">
           <!-- ^^^^^^^^^^^^^-->

or if you want to go link by click the just change type

 <input type="button" class="details-btn-profile" value="Profile">
    <!-- ^^^^^^^^^^-->

The url name chat_view_with_toid doesn't seem to exist in your urls.py.
