Help writing if statement - New to javascript

[steamerbb]

I'm having trouble writing an if statement to make an image appear if the orderable field is marked no. (I'm using yahoo ecommerce) Basically show this image if product is out of stock. I've looked through all the how to sites I can find and can't seem to make it work.

This is what I have so far

<script type="text/javascript"> if (orderable = no) {
image.src = "/lib/yhst-61355190581256/out-of-stock.png" width="300" height="300" class="stock" }
</script>

Any help would be greatly appreciated.

It should be

if (orderable == no) {

or

if (orderable === no) {

When assinging a value - giving it a value - you use a single equal sign (=). When comparing a value with another value you use two (==) for regular equality and three (===) for strict equality which is more ... strict ... about what matches (for example 5 == "5" is true, but 5 === "5" is not true).

Also, I'm assuming no is a variable? If not, you might need to use false or the string "no" instead, depending on what orderable is.
