HTML Field Trouble

Hello!
I read an interesting solution for placing a print button on form at http://www.gravityhelp.com/forums/topic/print-button. However, when I go into my form, place a HTML block and copy/paste the code, the button does not show up after saving the form. After refreshing the front end site to see if it worked, when I go back into the Form Editor I notice the code I pasted in is not longer in the HTML block.

I am sure this issue is simple to fix, but I can't seem to figure it out. I copy/paste the code into the HTML block, I select Content to 'Insert Variable.' I searched for additional information about the 'Variables' from the drop-down box and found http://www.gravityhelp.com/documentation/page/File:Html-properties.png, however this explanation does not include info on the Variables.

Any help would be appreciated on how to use the HTML block. Thanks!

Sure, the form can be seen on my testing site: http://www.gthemes.net/forms. The HTML block is inserted on the bottom of the first page on the back end, but it does not save when I update the form and it does not appear on the front end. Thanks for your help David!

Hey Rob, sent creds to your email. Let me know if the site doesn't email you. The form I was testing on was 'Form 3' and the front end display is at: http://www.gthemes.net/forms.

Feel free to test on whatever forms you want to- I am just playing around with different stuff and this is my sandbox site. Thanks!

Thats amazing! Thanks a lot for your help!

Drop the CSS you supplied above in the theme style.css, correct?
