When compile, the red line is
error, invalid lvalue in assignment
How to fix this?

Code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#define MAX 30

int main()
{
    int customerCount=0;
    char input[32];
    char drinks[MAX][10];
    char smallLarge[MAX][6];
    char hotCold[MAX][5];
    int i=0;

    printf("How many people are at your table?: ");
    fgets(input,32,stdin);
    sscanf(input,"%d",&customerCount);

    if(customerCount==0)
        {
        printf("END");
        exit(0);
        /*summary*/
        }

    printf("\n\nChoose what type of drink would you like.\n\n");

    while(customerCount!=0)
        {
        do
            {
            printf("Coffee, Tea, Cocoa, or Ovaltine?: ");
            fgets(input,32,stdin);
            sscanf(input,"%s",drinks[i]);
            }
        while(strlen(drinks[i])==0);

        do
            {
            printf("Small or Large?: ");
            fgets(input,32,stdin);
            sscanf(input,"%s",smallLarge);
            }
        while(strlen(smallLarge[i])==0);

        do
            {
            printf("Hot or Cold?: ");
            fgets(input,32,stdin);
            sscanf(input,"%s",hotCold);
            }
        while(strlen(hotCold[i])==0);

        if(strcmp(drinks[i],"None")=0)
            {
            printf("BILL");
            exit(0);
            /*print bill*/
            }
        }
