Remove an attribute from an expression

If you do any of the following actions, an expression no longer sets or reads an attribute:

• Delete all occurrences of the attribute name in the expression.
• Convert to comments all statements that use the attribute name in the expression.
• Delete the expression that contains the attribute.

Following these actions, the attribute keeps its value from the last time the expression executed and set its value.

The attribute doesn’t return to the value it had before the expression set it. To return the attribute to its original value, use the Channel Box or Attribute Editor to set the attribute.
