there are a number of if statements and a matching else for each
I have not verified whether each statement has its if, but there is definitely an else without an if. It is located at the very place of the error: 
 41      else {
 42         $hold = $hold.$hold;
 43     }
 44     else {

Do you see it?  else {...} else
