I don't know about the actual script working or even Javascript but as far as formatting goes...

I think it should be

if ( condition )
statement or block
else
statement or block

So...

<SCRIPT LANGUAGE="JavaScript"><!--
function cycle() {
if (question_1_yes = "true" & question_2_no="false" & question_3_no="false" & question_4_no="4" & question_5_yes="true" or "false")
document.write = "option 1";

else if (question_1_yes = "true" & qestion_2_yes="true" & question_3_no="false" & question_4_yes="yes" & qeuestion_5_yes="true")
document.write = "option 2";

else if (question_1_yes = "true" & qestion_2_yes="true" & question_3_yes="true" & question_4_yes="yes" & qeuestion_5_yes="true" or "false")
document.write = "option 3";

else if (question_1_yes = "true" & qestion_2_yes="true" & question_3_no="false" & question_4_yes="yes" & qeuestion_5_no="false")
document.write = "Option 4";

else
document.write "unfortunately we're unable to do anything."

//--></SCRIPT>
