Hello ,

I tried to add a Alexa Traffic Rank Button widget into my blogs sidebars .
We can generate the code from http://www.alexa.com/siteowners/widgets

When i added it as a text widget in sidebar , the content of the code just disappeared after clicking on save button .
Now the text widget become empty after saving ..

Am i doing something wrong ...
Please help me on this issue .
Is there any other way to add an alexa widget .

Thanks
