Yes Sir, tried that too.

But still getting the same error.

Which OS are you using?

Sir, the code (wt_matrix animation) is working fine.
Had another look at the entire code line by line & figured out that I did not delete some other code that I used for troubleshooting - which was causing the error all the while.

Thank you so very much for all the incredible support through out Sir.
