Need help with text widget and html input

I have an Aweber sign up form I would like to put in my blog’s sidebar and I tried to put it in with the text widget but somehow it erased all other sidebar widgets below it.

My blog is kevinpasco.com and I currently have my form in the text widget which is above all other widgets in the sidebar.

As you can see the only other widget that is being displayed below it is the sponsors one. There should be 6 other widgets displayed below that.

Should I use a different widget? What’s going on here?

Thanks a ton!
