:My roster system is not working properly. The calculation of time each staff member works is correct at times but then when I enter times in certain days it subtracts the hours instead of adding them.  The formula seems correct though.  I would also like the program to calculate how many hours I am using each day so I can see easily if I've made a mistake by putting too many people on or not enough etc. I seem to stuff it up when I copy and paste sections so I would like certain things to be protected so I can't stuff it up. I prefer to talk to someone over the phone before they start so I can explain the problems better. I am willing to pay for the phone call and top dollar to get this fixed ASAP  I am happy to email what I am using now so you can see the problem yourself
