>>>The X key oddly works well, not the Z though.
If you look at the traces ("wires" inside the PCB) you will see that 2, W, S, and X are all connected. That connection is the column.
There's lots of videos and web pages on "how keyboard matrixes work." Here's one:
keyboard matrix scanning shift register:

Find diagrams for the 2 boards. (Google search, images, for "Pro Micro pins" and "Elite-C pins" and make sure the names match.
There are pins in the microcontroller chip (IC). Some of these are brought out to the pins on the board.
If (making up an example here) pin 8 on the Pro Micro is D0, but on the Elite-C was B2 then the software
trying to drive the keyboard would not work.
>>>Also how would I check the code, what exactly would that mean?
The code Keeb.io is using for the keyboard would seem to be here:
https://github.com/qmk/qmk_firmware/tree/master/keyboards/keebio/quefrencyHere is the "keymap" file for your board:
https://github.com/qmk/qmk_firmware/blob/master/keyboards/keebio/quefrency/keymaps/default/keymap.c Column 3 of lines 18 to 21 shows that from the keyboards "point of view" 2WSX are all in the same column.
Looking here:
https://github.com/qmk/qmk_firmware/blob/master/keyboards/keebio/quefrency/rev1/config.h(not positive that's the right file. Is your board Rev 1??)
Line 38 says the 1st 3 columns of the left side are attached to pins F5, F6, and F7. So F7 is the pin that should be connected to 2WSX.
>>>I have a multimeter, in continuity mode how do I check the continuity from the switches to the pin? In other words, where would I place the prongs from the multimeter.
Go from the F7 pin on the Elite-C board (I don't know which that is... look it up) to the side of the switches that are tied together (follow green lines):
>>>Sorry for the really dumb questions, new to this hobby
Not so dumb. We all start out that way.
