The Problem Explained

In previously shared code, you define a component called PriceInput and attempt to access a function from its props like this:

However, when destructuring props at the start of your component, you must ensure that you're consistently using either destructured props or the full props object. If these two are mixed, you will encounter issues because the destructured variables will not contain the expected functions.

The error message you received is clear:

Here's a breakdown of how you can address this issue.

Solution: Properly Destructure Props

To resolve the error, you should consistently use either destructured props or the full props object. There's no middle ground; you must stick with one approach.

Step 1: Correctly Destructure Your Component Props

In your functional component PriceInput, instead of pulling out individual props, consider destructuring like this:

This way, all relevant props, including freqchange, are readily available without needing props. prefix when invoked.

Step 2: Update Function Calls in the Component

Step 3: Maintain Consistency

If you decide to keep the props as a single object, you can change the entire function's signature like so:
