This dialogue is for selecting interaction that needs to be calculated in a Design of Experiment.

The Matrix indicates that Column C (pink means error) can not be used because that it is be used by the interaction. A bigger orthogonal matrix is needed. The indication of errors in the array is only been displayed when the check-box

With a bigger matrix it is possible to calculate the interaction.

The not used Columns can be removed. This is the result with measure data.

Adding a extra interaction between D and G the interaction dialogue will indicate that there is an error because both interactions interact with each other.
