I don't understand what you're saying in the title of your question but the error message is very clear: you're trying to set the string property of your text6 control but that control does not exist anymore. Probably because you've closed the figure containing it.

Again I don't understand what you're asking. You need to explain better what it is you want.

All the controls on a figure are deleted when it is closed. There is no point in deleting them yourself beforehand, if that's what you're asking.
