Thanks! I inserted it just as you said, and it works.... sort of.
When I fill out the form, it still takes me immediately to the same thank you message, but it'll simultaneously try and slowly load the linked page (which is my blog page.) You can actually watch the little 'loading page' wheel on the website tab in the browser (I'm using Chrome) - it spins and skips a few times (it looks kind of glitchy) and then after about 15 seconds of that, it loads the page.
I've tested it about 4 times and it's doing the same thing each time. All the rest of the pages are loading just fine, without hesitation. It's just this one redirect that is lagging. Any idea what may be causing this?
Thanks again for your help!
