I'm supposed to make a delivery to a crazed botanist. In case you're curious, the shipping manifest is:

They told me the password to the front door is:

 -15    -13.06        -1    -4.13
   3     -2.67     -2.67       15
 4.5    -12.67    -11.75    -13.5
1.25         1        35       -9

When I arrived, I found a screen with a 4x4 grid, and four buttons below labeled

A S M D

How the heck am I supposed to get in? If this stuff isn't refrigerated, it'll go to waste.

Hint 1

Determine the sequence of button presses.

Hint 2

What type of item is each delivery?
