Doing some more work in culture grades , I think that I may have come across another small anomaly. I have, for instance, a number of species of the genus Dryopteris. In 'Culture Grades'/GA100S30CG, I highlight the first variety in the species, select the required grade and click on 'Species' in the 'Apply Buttons'. The grade is applied only to the first two varieties in the list. If I highlight the third in the list, the grade is applied to the rest.
If, in the first place, I highlight the third in the list, it again, applies the grade to the ones below it but not to the ones above.
Is this an easily solveable glitch George?
Thanks again for the alteration in 'Cultural Requirements' George. Have now been able very easily to make all the changes that I felt were needed - brilliant.
