So when I click on the Request Measurement button on this page the for will open in a light box but if I close it and try to reopen it the (<form id="mktoForm_1640"></form>) html will be stripped out. Here is the URL: https://lp.datacolor.com/ITMA-2019.html Any help is appreciated.

Hey Pat-It looks like you're running Bootstrap4 on this template and it might make more sense to leverage Bootstrap for the modal part and just put your form into that instead. Here's a link to more info on the Bootstrap modal: https://getbootstrap.com/docs/4.0/components/modal/ - there's copy/paste code there. This'll divorce the functionality of the lightbox and the form so you're more able to control from the modal (content/styling) without any kind of form (script) conflicts -- and it might help control the width of the lightbox as well.
