case structure error

[bulebell]

in the attachment，it show aerror，error code is A Case structure must have a case corresponding to every possible value of the selector. An easy way to fill this requirement is to specify a default case or cases whose selector values include ranges to or from infinity.

i can't understand where the error occur？thanks！

You have one case structure, that has two cases 'write' and 'read'.

Both case-names are in red because they don't match the selector data-type (an unconnected selector defaults to boolean allowing 'False' and 'True').

If you want to use a string as selector you need to add a 'default' case (or make one of the two cases default).

You could also add a Boolean as selector, making it a read or write boolean.

PS if you are in the error dialog (ctrl-L), you can double click on the error and you'll get send to the error.
