im using this function to detrmine a rate for a customer

my rate table (named rates) looks like this

code countyr rate1 rate2 rate n
011575 Colombia .23 .24 .28

what this function is doing so far is bringing me in the grid the correct name of the rate that im using for this customer..customer rates are preset in the customer table named long_distance.rate

what is the next step to compare using the if statements that i have underneath to the number dialed to detrmine the correct price uner the corrcect name...?
can anyone help me out here....
