EvaluationDate.split is not a function

It seems like you are trying to use the `split` function on a variable called `EvaluationDate` but it is not a string. The `split` function can only be used on strings, not on other data types like numbers or objects.

Make sure that `EvaluationDate` is a string before using the `split` function on it. You can use the `typeof` operator to check the type of `EvaluationDate`. If it is not a string, you may need to convert it to a string using the `toString()` method.
