[Closed] Array for Loop index error

– Comments –
/* Hello…I’m a beginner at scripting.
Trying to set up a rollout that will update the current vertex selected, and current frame number.
Having issues with ‘no vertex selected’ … errors out and I can’t figure out how to solve at roughtly line 31
Works fine as long as a mesh object and at least 1 vertex selected
