Recording of Twitter account name

I’d like to make a robot to follow twitter account from search result page.
But I couldn’t find a way to click names of twitter account.
It shows an error " Attach Browser ‘Follow Tw Page’ : Cannot find the UI element corresponding to this selector:"

The selector of click is
“webctrl aaname=‘MASON KAY‏ @masonkay1104’ parentid=‘stream-item-tweet-913752998001598464’ tag=‘A’ />”

Here is my workflow…
