Error in my read data

char temp[20];
sscanf(buffer, "%[^\n]", temp, buffer);
		if(isdigit(temp[0]))// check if what read in is a digit
		{
			while(r < 8)
			{
				sscanf(temp, "%*d%d", olympians[i].base_values[r]);

				for(int c = 0; c < 12; c++){
					sscanf(temp, "%d", olympians[i].scores[r][c]);
					tempScore[r] += olympians[i].scores[r][c];
				}
				tempScore[r] /= 12;
				if((olympians[i].base_values[r]) <= 3.1){
					tempScore[r] /= 2;
					tempScore[r] += (olympians[i].base_values[r]);
				}
				else
					tempScore[r] += (olympians[i].base_values[r]);

				olympians[i].total_scores[i] += tempScore[r]; 
			r++;
			}
		}

txt line im trying to read in:
1 7.5 -3 -3 -3 -3 -3 -3 -3 -3 -3 -3 -3 -3

is something wrong with

sscanf(temp, "%*d%d", olympians[i].base_values[r]);

because the compiler crash whenever i debugged this part
