Replaced broken wire but mic does not work.

Replaced broken wire but mic does not work.
My old cat chewed up the audio cable from the headset itself and bit through the wire. I found a 5 wire cable and bought some replacement 3.5mm TRRS jacks and replaced the whole wire and jack with them. The sound works perfectly fine but when i try to test the mic, it doesn't pick up anything. I wired everything up in the way its supposed to be wired up. Ideas anyone?
