HI, I've to produce some spreadsheet with hous and minuts and cells MUST contain numbers like -03:12,10 ( result of calculation : difference between 2 cells) Instead of that, I get 23:56:47,90 . It is the difference between 24:00:00,00 and that number.
I offered a proposal based on groups of 2 cells but I was told it is not the answer to the question.... because everything must be on the same cell. It HAS to be a number. I glanced at all HOW TO and found no answer. Can somebody help me ?
