Lucille's spreadsheet works... however apparently some who download it get some detritus saved by others, where they have overridden the formulas in the spreadsheet by typing numbers over them. This will result in wrong answers. (I got that when I downloaded it - someone had typed over one cell which threw off the answer for one of my clues.)

IMHO and all respect to Lucille... you don't need a spreadsheet. I've posted a low-tech way of solving but Berserker pointed out that it is all provided in-game.

SPOILER:

The inner circle of numbers is fixed. Spin the outer circle to match your clue. Note the numbers from your flowers, and the mapping given by the inner circle to outer circle of numbers. Then dial them in one at a time and hit the button.

I will still say that the clues don't matter.There are a total of 10 ways to solve the puzzle, including the identity (which would have a clue of x=x like 1=1 or something like that). You can do an exhaustive search without wasting very much time. Here's how:

Get your flower numbers (count the clumps, not individual flowers.) You will get three one-digit numbers x y z. You can start anywhere, but the example I give says start from x y z + 1. So dial in x+1 and hit the button, y+1 and hit the button, z+1 and hit the button. If it goes "bump!" and nothing happens then move on to x+2, y+2, z+2. The only trick is, if you get a two digit number like 11, just take the last digit and call it 1. Carry on adding one more to all the numbers... Repeat up to 9 times until the puzzle unlocks. Trust me, it will.
