Setting the html property sets the text and styling of the text element. Any text that the element already contained is replaced.
Getting the html property returns the element’s text, including HTML tags.

$w("#yourElement").html = "<b>Bold Text</b>";
To set or get the plain, unstyled contents of a text element, use the text property instead.
Just assign it to your input field’s value
for example:
$item(text1).text = $w('#firstName').value
