A context expression has multiple references that conflict
Explanation of error:
This formula includes an expression within square brackets that contains more than one reference that conflict with one other.
Example:
Task[1088>1]
In this example, the expression within square brackets contains two different references that are invalid when referring to a task.
How to resolve this error:
Examine the expressions within square brackets and ensure that they do not contain conflicting references.
The expression in the above example could be corrected by replacing the text in the square brackets with a valid task reference, for example [1088], resulting in Task[1088].
