try removing formatex in next line and in menu_additem use "" sometimes compiler gives completely wrong line

Is there "Level" constant in any other Enumeration in your code?

[WOASRY]

this?

[klippy]

Prefix all your Enumeration members. A constant is not namespaced when you define it in an Enumeration, it's still in the global namespace. Each time you define "Level" in another Enumeration, you are actually redefining "Level" and just putting another tag to it (hence the tag mismatch warning too).
