This error is thrown because the code is not correctly referencing the slides in the presentation object.

Step-by-Step Solution

Here's how to resolve the "Object doesn't support property error" error in your VBA code.

1. Check Object References

It's crucial to confirm that you are using the correct object names in your code. In VBA, when you declare your objects, you need to ensure that they are correctly set. Here’s an improved snippet:

Conclusion

By following the steps detailed in this guide, you should be able to effectively resolve the "Object doesn't support property error" in your Powerpoint VBA project. As a reminder, always ensure your object references are correctly declared and your XML syntax is correct for a successful implementation.
