Javascript Error???

Can someone please tell me what is the cause of this error (see attached screen shot).

Thanks,

The if(document.getElementById) you have - what is that supposed to do??

Are you trying to see if "boxdescription" exists as an element?

If so you would want to do if(document.GetElementById("boxdescription")) instead.

But regardless - that error is saying that .innerHTML is not an object on what is to the "left of it".

I use FIREBUG to debug the JAVASCRIPT while running in the browser - so these types of issues are easy to see in the WATCH and CONSOLE windows...

I removed the "value" and got the same error. No difference!

How is boxdescription defined on your page?

Is that IF statement helping you be cross-browser?

Why not use jQuery for that - it's really helpful in that regard.
