um what i mean is that some training needs to be done every 3 years some every 2 years some every year, but as there are different training sessions conducted on different dates, everybodys training will expire on different dates, what i want is that if the training is to be conducted every 3 years, the cell where the original date of training is to go orange when 3 months to expiry yellow one month to expiry and red when expired, im guessing this will be different again if the training is to be conducted every 2 years???
