Temperature Converter Problems

Hi everyone,

I'm sure that this will be a relatively simple questions for you experts, but I'm thoroughly confused trying to code this program. I have been assigned in school to create a temperature converter that converts celsius to farenheit and vice versa. I tried searching for code on the net, but none of the examples that I found use the same formula that I'm required to use. I must use the following formulae:

°F = (40 + °C)*9/5 - 40 and

°C = (40 + °F)*5/9 - 40

This is the code that I'm trying to insert this formula into:

___________________________________________________________

<INPUT TYPE = "text"

NAME = "cels"

VALUE = "0"

SIZE = "3"

MAXLENGTH = "3"

onChange = "fahr.value =

**Math.round(40 + this.value * 9.0/5.0 - 40);">** ° <STRONG>C</STRONG>

<STRONG>equals</STRONG>

<INPUT TYPE = "text"

NAME = "fahr"

VALUE = "32"

SIZE = "3"

MAXLENGTH = "3"

onChange = "cels.value =

**Math.round(40 + this.value * 5.0/9.0 - 40);">**

° <STRONG>F</STRONG>*

_____________________________________________________________

The outputs are not correct, and I just can't figure out how to arrange this formula so that it works. Any help that you could give me would be greatly appreciated!

Thanks,

Matt
