hey，

Could you tell me what is wrong with this code，the print file says that symbol is undefined.I can‘t understand why it is wrong.

The 3rd picture is the command reference example. My do loop nest is similar to the example.But why is it wrong ? And please tell me how to modify it

Best regards

    Hi there,

    The way symbol works means that etx$I$J is being evaluated as etx$I1 for the first iteration and is then looking for I1 which does not exist. This happens because the last symbol is evaluated first. See this article for more details.
