 # \<member> in class \<class> cannot override \<baseMember> in class \<baseClass> because an intermediate class \<intermediateClass> overrides \<member> in class \<baseClass> but is not accessible.
 
+**Error ID:** BC30981
+
 ## To correct this error
 
+- Change the inheritance structure to directly inherit from the base class instead of going through the intermediate class.
+- Make the intermediate class accessible by changing its access modifier to `Public` or an appropriate level.
+- Override the member at the appropriate level in the inheritance hierarchy where it is accessible.
+- Review the class design to ensure proper access levels throughout the inheritance chain.

+**Error ID:** BC31538

 ## To correct this error
 
+Review the access levels of the base member in the referenced assembly to determine the appropriate modifier. Ensure the overriding member does not expand the accessibility of the base member being overridden. For example, change the access modifier from `Protected Friend` to `Protected` for the overriding member:
+
+```vb
+' Instead of Protected Friend (which expands access)
+Protected Overrides Sub MyMethod()
+' Use Protected (which matches the base member access level)
+```
