Hi and thank you for you response.
I read every post and look for any video and I still can get what am I doing wrong.
I abandoned the I dea of Iframe and just want to shoe embedded website in the html box. This is what I did:
In the data base: created a field (URL type):

In the dynamic page: insert an “embed a site” element:


$w(“#dynamicDataset”).onReady(() => {
const EngMap = $w(‘#dynamicDataset’).getCurrentItem().EngMap;
$w(‘#html4’).src = EngMap;
});
});
Published the site
Getting:
Wix code SDK error: The url parameter that is passed to the src method cannot be set to the value . It must be of type url

And gray html box…
Please help…
