For options C, D the value doesn&#39;t vary.</p> <p>I started using Eval Function, to solve this. The formula is working fine when I tried to preview before publishing. But when I try to publish its giving me this Unsupported expression error :</p> <p>&quot; The following expression could not be parsed because of a syntax error or because it uses an undefined namespace prefix or unsupported function : . &quot;</p> <p>Any ideas are appreciated.</p> <p>Thanks.</p></div></div>
