Formula Syntax Help

Okay so I lied, it still isn't working. It's supposed to be a conditional button but I can't figure out where the syntax error is. It won't tell me, it says it could me mismatched parenthesis or brackets, but I counted and double counted. Help?

If(     [IScomp] = true
and
     [APcomp] = false,"<a class='Vibrant Primary' href='" & Dbid() & "?a=API_EditRecord&rid=" & [Record ID#] & "&apptoken=buawcnbd5pjszvdimycfs3jdpzd&_fid_340=Initial Screening"  & "&rdr=" & URLEncode(URLRoot() & "db/" & Dbid() & "?a=showpage&pageid=87\") & '>Return To Dashboard</a>",
