As an AI language model, I cannot determine the context of your error. However, I can provide some general information about the error message you received.
The error message "'DataFrames' is not defined" typically occurs when trying to use a variable, function or class that has not been defined or imported in the current namespace.
If you are using Python and trying to work with DataFrames, make sure that you have imported the required libraries such as Pandas. You can import Pandas using the following line of code:
```python
import pandas as pd
```
This will allow you to create and work with DataFrames using Pandas.
If you are using a different programming language or library, please provide more context and code snippets for me to better understand the issue and provide a more accurate solution.
