Two embedded codes on one page not working

id attributes need to be unique across a page.

<iframe src="https://app.donorview.com/e80YM" frameborder="0" scrolling="no" id="dv-iframe" name="dv-iframe" width="100%" style="width: 100%;"></iframe>

When you use the same id more than once then the last one takes precedent.

You need to change the ids ( id="dv-iframe" ) for each iframe to be unique. Something like id="dv-iframe-1" and id="dv-iframe-2". Then you need update the scripts similarly. '#dv-iframe-1' and '#dv-iframe-2'.

Let us know how it goes.
