According to your code, I can't reproduce your problem.
But as far as I know, The namespace x already contains a definition for x error is usually caused by the other namespace contained a enum with the same name. So please check if your code contains the same name "Dep".
If you still can't solve your question, please post your complete code.

It seems you declared already something named Dep (maybe a class ?) in the same namespace. Change the enum name or use the "Object Browser" to see if this is not declared alrady in some other file.
