Reading a matrix in C

I’m trying to make a program in C that reads my matrix and calculates the sum of elements,
but it gives me an error at scanf("%d",&a[i]). This is the error :

      warning: format ‘%d’ expects argument of type ‘int *’, but argument 2 has type ‘int 
    (*)[10]’ [-Wformat=] 

and this is my code:

#include <stdio.h>

int main() { 
    int m,n,a[10][10],s=0;
    scanf("%d",&n);
    scanf("%d",&m);

    for(int i=1;i<=n;i++) 
        for(int j=1;j<=m;j++)
            scanf("%d",&a[i]);
 
 
    for(int i=1;i<=n;i++)
        for(int j=1;j<=m;j++)
            s=s+a[i][j];
    
    printf("%d",s);
    
    return 0;
}

Anyone know why?

>Solution :

change scanf("%d",&a[i]);
to scanf("%d",&a[i][j]);
as you need to give him the address to write on but you give the address of array of ten int
