Two iframes not working

On a page, using text/html editor, I have inserted two iframes:
<iframe id=”a” and here I make a call out to google calendar iframe function></iframe>
<iframe id=”b” src=”https://mail.google.com/tasks/ig”></iframe&gt;

The first iframe works perfectly.

The second iframe makes a call out to a simple webpage that shows google tasks for a signed in user. What’s weird is that I can see that webpage easily in its own window, and if I put in cnn.com instead in the 2nd iframe, that works too. But as it stands above, I don’t get anything showing up in the 2nd iframe. I should note that both I frames are in a <table>.

Any suggestions? Thanks!
