[OpenLayers-Users] map scope problem

[S.Reena]

Hi ,

I  changed my code to use OpenLayers.LoadURL function like this

 OpenLayers.loadURL("reports1.html", '', this,afterreports)

In this reports.html file, I've made some dependent drop down boxes where
content of 2nd option box depends on selection made in 1st option box etc.
Also I am calling a php file which modifies the database in
 el.innerHTML="<iframe src=\"showtable.php\"+queryString height=100%
width=100% ></iframe>" 

Now the thing is that in afterreports function if I place the
response.responseText in a div , then 
the option boxes don't work properly but wms[8].setVisibility(true) works.
On alert(wms) it gives [object Object],[object Object], etc.


But if I make a OpenLayers popup and show response.responseText in that, the
option boxes work properly but wms[8].setVisibility(true) doesn't work and
alert(wms) gives ,,,,,,, etc.


What can be reason for this?

Thanks
Reean.
