Help - functionality broken for specifying html link.

In our form (http://goo.gl/1PFm) the "Terms and Conditions" text opened a html link in another window. 

This is now broken and I dont know why. I had the following script in place and TANDC was referenced in the text field. Help please?

TANDC =  "<a href='#' onclick=window.open('http://www.allweatherchildcare.co.uk/documents/AWC_TANDC_JAN01_V1.pdf');return false;>" + "Click Here For Terms and Conditions OF Business" + "</a>" ;
