 // Why will an error occur when this program runs?
 // =============> write your prediction here
+// decimalNumber is part of the function so it cant be set with const decimalNumber, the name needs to be different.
+// console.log(decimalNumber) causes an issue as well, decimalNumber is part of the function, it should request convertToPercentage for it to work.
 
 // 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
+// console.log(decimalNumber) will not work as decimalNumber is inside the function,
+// and "const devimalNumber = 0.5" has already been called from teh function. You need to change the name or apply the value in the call on consol.log()
+
 
 // Finally, correct the code to fix the problem
 // =============> write your new code here

+  const percentage = `${decimalNumber * 100}%`;
