incompatible pointer to integer conversion assigning to 'int' from 'string'

I am getting this warning when I am trying to assign a name to my array.

bool vote(int voter, int rank, string name) {
    
    preferences[voter][rank] = name;
    return false; }

I need to input a name in the function, that will move to the place of preferrences[i][j]. First time asking a question, so I am sorry if it is incomplete.

The full error:
