Twitter iMacro, help please!

Can someone tell me how to write an iMacro for this

I want to go to the following Twitter page

https://twitter.com/invitations/find_on_twitter

Then add a user from csv file (each one is a twitter username)

This will find the user, then I want to click on follow this user on the following page

Then start again.

I started with the following code but couldn't nut it out. Anyone?

VERSION BUILD=6500420
TAB T=1
TAB CLOSEALLOTHERS
URL GOTO=about:blank
TAB T=1

URL GOTO=https://twitter.com/invitations/find_on_twitter
SET !DATASOURCE C:\Twit.csv
SET !DATASOURCE_COLUMNS 1
SET !LOOP 1
SET !DATASOURCE_LINE {{!LOOP}}
TAG POS=1 TYPE=TEXT FORM=NAME:find_on_twitter ATTR=NAME:category CONTENT={{!COL1}}

Anyone?
