    Mean Median Mode Problem

    It has a compiling error and highloights the retunr (0); saying theres a syntax error before it. I cannot find the problem anyone care to help or improve my program.
    Code:
    #include <stdio.h>
    #include <stdbool.h>
    #include <time.h>
    #include <stdlib.h>
    #define ARRAY_SIZE 50
    
    void fillArray(int total, int nums[]);
    void sortArray(int nums[], int total);
    void printResults(double mean, double median, double mode);
    int findMode(int nums[], int total);
    int readTotalNums();
    double findMean(int nums[], int total);
    double findMedian(int nums[], int total);
    
    int 
    main(void)  
    {
        int nums[50];
        int total;
        double mean, median, mode;
        do{
            total = readTotalNums(); //guarantee 1-100
            fillArray(total, nums); //read in the #s don't need to check range
            sortArray(nums, total);
            mean = findMean(nums, total);
            median = findMedian(nums, total);
            mode = findMode(nums, total);
            printResults(mean, median, mode);
           }
        return (0);
    }
    
    
    void fillArray(int total, int nums[]) 
    {
        int temp;
        int i;
        printf("Please enter %i numbers\n", total);
        for (i = 0; i <= total-1; i++) {
            scanf("\n%i",&nums[i]);
        }
    }
    
    void sortArray(int nums[], int total)
    {
     int x;
     int y;
     for(x=0; x<total; x++) {
        for(y=0; y<total-1; y++) {
            if(nums[y]>nums[y+1]) {
                int temp = nums[y+1];
                nums[y+1] = nums[y];
                nums[y] = temp;
            }
        }
     }
    }
    
    void printResults(double mean, double median, double mode) 
    {
        printf("Mean: %lf\tMedian: %lf\tMode: %i", mean, median, mode);
    }
    
    int findMode(int nums[],int total)
    {
        int i, j, maxCount, modeValue;
        int tally[total];
        for (i = 0; i < total; i++) {

        do {

                return (nums[total/2]+nums[total/2-1])/2;
            }else{
                return nums[total/2];
            }
    }

    You are forgetting while(condition); at line 29.
