I use following script but nothing happens

public InputField BasePrice; //assign base price input field here
 public InputField SellingPrice; //assign selling price input field here
 public Text Profit; //assign profit text here
 void cal()
 int BP = Convert.ToInt32(BasePrice.text); // convert it into integer
 int SP = Convert.ToInt32(SellingPrice.text); // convert it into integer
 int P = SP-BP; // do the calculation, find the result
 Profit.text = P.ToString(); //turn result back into string and display it in the profit text


it looks like it should work but it doesnt. after I enter value in SP & BP and hit enter, nothing happenes. please help. thanks in advance.
