'#ExternalSource' directives cannot be nested
You attempted to place an #ExternalSource directive within another #ExternalSource block. The #ExternalSource directive references outside code, enabling the compiler to accurately report when exceptions occur within that code.
#ExternalSource blocks cannot be nested within other #ExternalSource blocks.
Error ID: BC30580
To correct this error
- Move the inner #ExternalSource directive outside the enclosing #ExternalSource block.
