Passing variable to iframe

[peaforabrain]

I am having trouble exercising this function, and wondered whether anyone would be kind enough to help.


I have a php/mysql output that i would like to pass to an iframe in order for a form to work better.

This is my code;

function countyChanged(name)
{
if(frames['editregion'].document.r1.r2.value)
  {frames['editregion'].document.r1.r2.value = name;}
    document.getElementById('listingsearch'+'r1').submit();
}

The

('listingsearch'+'r1' )

is my problem, as I can get the variable to pass using a simple form and submit button, but it doesn't work using the onChange command, so I have tried this so as to get the variable passed and the iframe page to refresh in order to activate the php function in the iframe.

Sorry if this sounds confusing.

Can anyone help?
thanks

I managed to fix this problem by changing the onchange command to include value in its operator.

So, I got the variable passed to the iframe, and now the function can display its new selection. Now, I need to pass the new variable back to the parent and to another iframe, where it can perform the same thing.

Can anyone offer an idea?

thanks
