Again, When you define this cell as a CONSTRAINT cell, Best

Therefore, your CONSTRAINT cell would contain the following:
0 < or = 16 - C5
convert it (by subtracting C5 from both sides) to:
In order for Best Answer‚Ñ¢ to use this information you need to

You have a restriction that production time (C5) cannot exceed 16
Here's another example of setting up a CONSTRAINT cell:

Best Answer‚Ñ¢ will make its usual assumption; that this value must
=C5-250
Therefore, your CONSTRAINT cell would contain the following:
C5 - 250 > or = 0
convert it, using basic algebra (subtract 250 from both sides), to:
