C program skipping a scanf for a float?

Everytime I go to the option to enter the costs it skips the float inputs.. URGENT...

Code:

void service_cost(void)

{

float hwcost;

float swcost;

float tcost=0.00;

float labourcost;

FILE *fp2;

printf("\t*********************************************************************\n"); //printf statement

printf("\t*********************************************************************\n"); //printf statement

printf("\t*** Service Account ***\n"); //printf statement

printf("\t*********************************************************************\n"); //printf statement

printf("\t*********************************************************************\n\n\n");//printf statement

printf("Please enter hardware cost\n");

scanf("%.2f", &hwcost);

printf("Please enter the software cost\n");

scanf("%.2f",&swcost);

printf("Please enter the labour cost\n");

scanf("%.2f",&labourcost);

tcost = (tcost + hwcost + swcost + labourcost);

printf("The total service cost is %.2f\n", &tcost);

fp2=fopen(Services,"a+");

fprintf(fp2,"The hardware cost is: %.2f\n",hwcost); //writes to file

fprintf(fp2,"The software cost is: %.2f\n",swcost); //writes to file

fprintf(fp2,"The labour cost is: %.2f\n",labourcost); //writes to file

fprintf(fp2,"The overall cost is: %.2f\n", tcost);

fprintf(fp2,"................................................\n");

fclose(fp2); //close file

system("PAUSE");

system("cls");

serviced();

}
