You found one of the warts in psp. Since your for loop contains no 
further python statements, the parser gets confused. Try adding a single 
comment at the beginning of your for loop:

<p> some text for the page </p>
<%
for r in Results:
     # begin indentation - comment fixes the syntax error
%>
I got the result <%=r%><br>
<%
# end indentation
%>
