Hi Mohamed,

The error message "Deletion requires an existing variable" indicates that the variable "textBBoxes" has not been declared.

To resolve this issue, please ensure that you run all the sections in the specified order as outlined in the example. Rather than executing each section individually, you can run all sections simultaneously by using the "Run" button located under the "Live Editor."

Furthermore, you may use the following command to load the example and ensure that all sections are correctly in place:

openExample('vision/TextDetectionExample') %Internet connection is required

Hope this helps!
