javascript errors; help with debugging a simple script

hi there

the following script generates an error that reads ".... line 28 is not a 
number" when the functions are called. since i can't figure out where 
line 28 is (how does javascript count line numbers, anyway?), and the 
script looks okay to me, what's wrong? please respond ASAP.

function goBack()
if (parent.right.history.go(-1) == null)
  alert("You haven't gone anywhere yet")
else (parent.right.history.go(-1))

function goForward()
if ((parent.right.history.go(1) == null) && (parent.location.right 
else (parent.right.history.go(1))

which is used in two buttons

<input type="button" value="Back" onClick="goBack()">
<input type="button" value="Forward" onClick="goForward()">
