The lines above are two complete statements.

The "else" is not allowed to start a statement.  You need to make sure 
the "if" is incomplete when you start the line containing else.  The 
usual style is

if (cond) {
   stmt1

# The if is still incomplete, because the closing brace is missing

} else {

# now the else will be accepted

   stmt2
}
