Here is my exercise: quote: Write a progarm to calculate the interest on a bank account. The interest is: 0% on balances <$1000 1% on balances <=$1000 and <$5000 1.5% on balances <=$5000.

But I think logically first one is good way to deal with this question. Do you see anything wrong??? code: function cal(){ if(5000<=form1.acc.value){ form1.int.value=Math.round(0.015(form1.acc.value-5000)+40); }else if((1000<=form1.acc.value) && (form1.acc.value<5000)){ form1.int.value=Math.round(0.01(form1.acc.value-1000)); }else if((0<=form1.int.value)&&(form1.int.value<1000)){ form1.int.value=0; }else{ alert(" Work hard!!!"); } code: function cal(){ if(form1.acc.value<0){ alert("Work hard!!!"); } if(5000<=form1.acc.value){ form1.int.value=Math.round(0.015(form1.acc.value-5000)+40); }else if((1000<=form1.acc.value) && (form1.acc.value<5000)){ form1.int.value=Math.round(0.01(form1.acc.value-1000)); }else{ form1.int.value=0; } Thanks.

Are you sure you didn't mean if (form1.acc.value <= 5000) ?

Hi, guys. Could I ask you other question?
Here is my exercise:

quote:
Write a progarm to calculate the interest on a bank account. The interest is:
0% on balances <$1000
1% on balances <=$1000 and <$5000
1.5% on balances <=$5000.
As user error detection, if user enter negative number, get alert saying "Work hard!".

I cannot understand why this code does not work. Then I modified like secode code. Works fine. But I think logically first one is good way to deal with this question. Do you see anything wrong???

code:

function cal(){



              if(5000<=form1.acc.value){



                  form1.int.value=Math.round(0.015*(form1.acc.value-5000)+40);



                     }else if((1000<=form1.acc.value) && (form1.acc.value<5000)){



                          form1.int.value=Math.round(0.01*(form1.acc.value-1000));



                          }else if((0<=form1.int.value)&&(form1.int.value<1000)){



                                form1.int.value=0;

                       

                               }else{



                                      alert(" Work hard!!!");

                                    

                                    }

code:

function cal(){



              if(form1.acc.value<0){



                     alert("Work hard!!!");



                         }



              if(5000<=form1.acc.value){



                  form1.int.value=Math.round(0.015*(form1.acc.value-5000)+40);



                     }else if((1000<=form1.acc.value) && (form1.acc.value<5000)){



                          form1.int.value=Math.round(0.01*(form1.acc.value-1000));



                          }else{



                                form1.int.value=0;

                       

                               }

Thanks.

if(5000<=form1.acc.value)

Consider if the input's value is, say, 1000:

if (5000 <= 1000)

5000 is not less than or equal to 1000, so the if block won't be entered.

Are you sure you didn't mean

if (form1.acc.value <= 5000)

?

Yeah, I am sure about that, Slime.
How are you today?
Well, I fixed this problem.
You told me to put parseInt when I deal with If statement.
I did that.
Then worked.
Many thanks.
