Copying files in bash

Question

Im learning bash and I have a question about how to copy files from fatherly folder into another folder when user types "0". (for example from K2 to K1) And I don't know how to do so.

#!/bin/bash
echo $1 $2 $3 $4
K1=$1
K2=$2
if [ $4 -eq "0" ] then
cp -v ../$2/*.{png,bmp,jpg,xcf,pcx} .
cp -v ../$2/*.{png,bmp,jpg,xcf,pcx} ./$1
fi

that's all I wrote, could you help me..?
