 // Why will an error occur when this program runs?
 // =============> write your prediction here
+//There are two errors in the code. Firstly the variable decimalNumber is being used as a parameter to the function but is then  redeclared in the function. Secondly the console log is trying to access a variable that is not in its scope.
 
 // Try playing computer with the example to work out what is going on
 
-function convertToPercentage(decimalNumber) {
-  const decimalNumber = 0.5;
-  const percentage = `${decimalNumber * 100}%`;
+// function convertToPercentage(decimalNumber) {
+//   const decimalNumber = 0.5;
+//   const percentage = `${decimalNumber * 100}%`;
 
-  return percentage;
-}
+//   return percentage;
+// }
 
-console.log(decimalNumber);
+// console.log(decimalNumber);
 
 // =============> write your explanation here
+//line 9 creates a a new variable called decimal number, then on line 10 the code attempts to declare a new variable with the same name and thus a syntax error is thrown.
 
 // Finally, correct the code to fix the problem
 // =============> write your new code here
