problem with 'if-elseif-else'

In order to show the appropriate root for the problem I created this code :

   if riza > 1 | riza<0  
  fprintf('so the correct root is',root1)
  elseif riza1>1 |riza1<0 
  fprintf ('so the correct root',root)
  end

Even though it appears the message 'so the correct root is' ,it won't appear the root1 or root.How can this be fixed ?

% code
 if riza > 1 | riza<0  
fprintf('so the correct root is %f\n',root1)
elseif riza1>1 |riza1<0 
fprintf ('so the correct root %f \n',root)
end
