I have on cell that has an original manfg. date 1/1/90 (this date will
change) the next hydro date is either 3 or 5 years depending on the date.
prior to 1/1/91 cylinder must be done every three years and after 1/1/91 they
must be done every 5 years. I am stuck on the formula asd I have it now
=IF($D$3<B16,1095+D3,1825+D3) any assitance would be of great help.
Thnaks
