Hey,
You can transfer the company name by sending over the data to the lightbox like this:
$w("#myButton").onClick( (event) => {
let data = {
companyName: $w("#hereGoesTheCompanyName").text
};
wixWindow.openLightbox("LightboxName", data);
});
Then on the lightbox you can set a text element’s value to the company name like this
$w.onReady( function() {
let data = wixWindow.lightbox.getContext();
$w("#textElement").text = data.companyName;
} );
