Script not working in iFrame. Options

[P6tu]

Hello,

So I've figured out a lot on my own and by googleing, but now I'm at a point, where I can't even find an answer from Google.
I've built this page from scratch over the years and I've been improving it step by step. This is the page I'm talking about:
Classic Rent
So I'm trying to move all my active information in the center column also to an iFrame. I haven't had any issues with iframes and scripts so far, but now I can't seem to be activating them all.
Test page
As you can see, then compared to the homepage, then the slideshow isn't working on the test page iFrame. Why is that?

And maybe there are people here, who could say, is it possible to change two different iFrames with a single navigation? Currently when browsing my webpage, then the heading changes the title accordingly. When I move my information from the center column to an iFrame, then I do not know, how would I be able to change the heading also, when navigating to a new page (new iFrame) from the left menu.

With best regards,
P6tu

Hello Pandy. Thank you for your help =). I got the script thing worked out already.
I'm just trying to figure out the iframes without the script. For some reason if I use the iframes without the script as shown in your referred webpage, then I can't get the parent pages CSS applied to the page in the iframe.
Anyway, it's been a long day for me too - my head hurts already and I've ran out of good songs in my playlist .

Every year I improve my page - this year has just begun . I have a lot of time and a lot of things to improve. But one step at a time - good things take time to create =).

Good night for now and thank you!
