Joomla iFrame and IWP

[larine]

I have embedded my database into my website through the use of an iFrame. Now, I'm getting this error:

Message: 'top.iwp' is null or not an object

Line: 50

Char: 27

Code: 0

URI: https://www..

I have tried to find a solution for my problem but to no avail. I see that this topic was discussed in http://fmforums.com/forum/showtopic.php?tid/201373/post/318242/hl/javascript/fromsearch/1/

but it doesn't seem that they have come to any clear conclusions?
