Calculating extra time for students taking tests with disabilities

Hello, I'm in need of sage advice once again the community has been so helpful and patient with a newbie like me! I am trying to incorporate this little calculator ihttps://code.mathforge.org/ExtraTimeCalculator/ into my survey so I can use it to help faculty accommodate students who need more time on tests. I want to use the output as embedded data but so far the only way I am able to make it work on my survey is with this, but it will not let me create embedded data from the result: <iframe src="https://code.mathforge.org/ExtraTimeCalculator/" height="385" allowTransparency="true" frameborder="0" scrolling="no" style="width:100%;border:none;"></iframe> Any help would be greatly appreciated!
