Remover indicator and get error

[JTizz]

I get this error when trying to remove indicator?

Hello,

Thanks for writing in today.

Do you have another indicator named ES that could be using this as part of it's programming logic? You'd need to remove this first.

If this is a workspace named ES then I'd suggest closing the workspace first or removing any instance of the indicator on this workspace before attempting to remove the indicator.

Please let me know if I may be of any further assistance.
