Can’t figure out the lightbox shortcode

Hi,

I hate to admit it but I can’t figure out how to use the lightbox or lightbox content shortcodes to display another shortcode (frontuser uploader, which displays a form).

It looks good on preview but then on the page there is either nothing there or it shows like normal text.

This is what I’m using:
[su_lightbox type=”inline” src=”#library-submission-form”][su_lightbox_content id=”library-submission-form” text_align=”left”][FORM SHORTCODE HERE][/su_lightbox_content][/su_lightbox]

Ideally I’d like to use the button, which when clicked opens up the lightbox with the form, but I can’t figure that out either.

Any help would be appreciated!
