Help with mel script is not working with Maya 2024

triton

I was using this Mel script to switching between different camera angles for years but when I updated to Maya 2024 it stopped working.

Can you please help me to fix it?

Thank you.

You can use it when you put the script in a .mel file in your maya\2024\prefs\scripts directory.
And you can launch it with the Mel command: switchCam 1

The error I am getting:

// Warning: float $minAngle = `angle $wupv <<1,0,0>>`;

// Warning: Line 118.45 : Redeclaration of variable "$minAngle" shadows previous declaration at line 80. Previous value will be overwritten by explicit initializer.
