Hi Erick thanks for your help and the examples you gave me I have used one that is getfeatureinfo-popup.html and when I click the popup box open but there is an error message<br><br>
msWMSFeatureInfo(): WMS server error. Requested layer(s) are not queryable.
<br><br>You know I'm workin with Mapserver and reading on the Mapserver website I found I need some parameters in my mapfile layer in order to make it work but I can't make it work so here is my layer code please if you could help me to find the problem or maybe is another problem so could you give me some ideas.<br>

I found information about vector and gml layers with text format but I would like to know how to use them to work with more than one layer or if there are other solutions that someone could recomend.<br>

</div></div>Hi. Have you considered using the WMSGetFeatureInfo control? You can<br>
check out the getfeatureinfo-control example<br>
