receive values from open.window()

[allegrande]

Hey,
first of all, this is a great component, and has helped me a lot!

I have made a simple form (BreedRegist) with a button "open map" (it opens ' kart.html' with open.window()),
where users can place a marker. When the users click add, the values should be stored in
the two hidden variables lng and lat in the BreedRegist-form.


But when I click "add" I get this error
Error: window.opener.document.BreedRegist has no properties

My form name is BreedRegist and the hidden-field names are lng and lat

Here is part of the code inside kart.html:

Code:

function add(longitude,latitude) {
  if (window.opener && !window.opener.closed){
    window.opener.document.BreedRegist.lng.value = longitude;
    window.opener.document.BreedRegist.lat.value = latitude;
  }
  window.close();
}

<input type="text" id="location_lat" style="width:10;" >
<input type="text" id="location_lng" style="width:10;" >
<span onclick="add(document.getElementById('location_lng'),document.getElementById('location_lat'));">add</span>

please help me
thx

In order to address the form, don't use the form name. The form is named ff_form99 where 99 is the number you find in the column ScriptID in the Manage Forms screen. You can check this f.i by looking at your page's source.
