working with an array that is a float

[Robbo99]

/*hi the answer to this is proberly really easy
i am trying to multiply a bit of data from the array by an integer*/

float data[40][7] = {
{1, 20, 1.6, .873, 111, .00608}, /*.....etc*/

deadload = t*(data[j][3]) + c*(data[i][3]);

/*i, j, c and t are all integers deadload is a float the program doesn't error but the output is addresses i think*/
