jrbautista on "cannot link"

Hi. It's been two days that I can't link in my blog. If I have this list of post (table of contents):

http://math4allages.wordpress.com/view-posts-by-topics/

I've been linking the text Making Sense of Exponential Growth here:

But no result. Been repeating it over and over for the past 3 years.
