I'm a new to this, but maybe somone will help me. I've an excelsheet with:
colom A: dates (every day from a whole schoolyear)
colom B: hours of class 1 (every day of the week for the whole year)
colom C: hours of class 2 (every day of the week for the whole year)
colom D: hours of class 3 (every day of the week for the whole year)

I would like to do the following:
I put in cell F1 the amount of hours a pupil may work on a certain job.
I put in cell F2 the startdate of the job.
I put in cell F3 the class (1,2 or 3)
When I push a button, I would like to see the date when the job had to be
finished....

Is this possible?

Thanks in advance for the reactions on this difficult question in bad
English.

René.
