Trouble with my code (IF , ELSE)

Question

Having technical issues with this line of code. I want it to first calculate the BMI than determine if weight is over 25 tell patient that they are overweight. If under 18.5 they are underweight. Cant Seem To get the function right.

var calculate 
var test;
calculate = document.getElementById("answer");
calculate.innerHTML =  (weight/(height*height))* 703;

if(calculate > 25)
{
calculate = document.getElementById("answer06");
calculate.innerHTML = "you are fat";
}
else if(calculate < 18.5)
{
calculate = document.getElementById("answer06");
calculate.innerHTML = "you are to skinny";
}

You also have a missing semicolon on line 1 `var calculate;` — Thomas Sebastian, Oct 17 '14 at 04:39
@ThomasSebastian JavaScript actually has a nasty little feature where lines [automatically have a semicolon added](http://stackoverflow.com/questions/2846283/what-are-the-rules-for-javascripts-automatic-semicolon-insertion-asi). — Marty, Oct 17 '14 at 04:40
Yeah it does Marty. Just better to keep up with good coding practices. Don't you agree? :) — Thomas Sebastian, Oct 17 '14 at 04:43
@ThomasSebastian Of course, just wanted to flag that the lack of `;` would not affect the code whatsoever in its current state. — Marty, Oct 17 '14 at 04:44

var bmi = (weight/(height*height))* 703;
calculate.innerHTML = bmi;

if(bmi > 25)

Update:

var bmi = (weight/(height*height))* 703;
document.getElementById("answer").innerHTML = bmi;

if (bmi > 25)
{
    document.getElementById("answer06").innerHTML = "you are fat";
}
else if (bmi < 18.5)
{
    document.getElementById("answer06").innerHTML = "you are too skinny";
}
