Well i used the Dynamic Iframe script to help.
Under a normal frame, you would need set the height... not the problem here is... height="100px" or height="auto" does not work.. and should one of your visitors or members have say 500+ contacts not all could show... so by using the dynamic iframe script the frame will re-size depending on the needs of the end user.
I don't suggest using in a standard iframe, the above method works fine, i will take note of comments on this thread and implement some new methods / ideas as i update this but as it stands it's working fine and doing what it says it does
