Is Solver capable of solving my problem?

[ishanruwala]

I've got a design spreadsheet where the user has to manually input values (by guessing) to get the design to work. I've got several IF statements that need to be met ("okay" vs. "not okay" return) in order for the design to be acceptable. The cells in blue are the inputs. Can I have Solver determine what values for the inputs will result in each requirement being "okay" (or L3="1")? The inputs have restrictions/parameters however:

D6 must be a whole number between 20-22
I6 must be a whole number between 10-12
D7 must be a whole number
D8 can be a decimal number between 0.25-0.75

In other words, I need Solver to give me the inputs (within the parameters mentioned above) that will result in L3 being "1". L3 returns "1" if ALL the individual requirements are met and "2" otherwise.
