Calculated Checkbox field to compare 2 fields

Hi everyone, 

I need to create a checkbox field that

  • will be checked IF the amount of a field is greater than the amount in another field.
  • will not be checked IF the amount of a field is less than the amount in another field.

All the formulas that I have tried with ifElse and greaterThan are coming back with errors. Would anyone know how to write this formula? 

Thank you in advance.
