Ok so i have this code to update the position of my iFrame(does that have a capital?):

document.getElementById("reportBox").style.left=(getdimensions(0)/2-250)

i have tried various different versions including:

document.getElementById("reportBox").style.left =(getdimensions(0)/2-250)+".px"

but it isn't working.

firefox error:
Warning: Error in parsing value for 'left'. Declaration dropped.
Line: 0

iFrame code

<iframe height="0px" width="0px" style="position:absolute;" id="reportBox" scrolling="no" frameborder="0"></iframe>

Any help will be greatly appreciated.

Thank you

And is the prototype.js framework where the getdimensions() function (Which BTW should be getDimensions() as JS is case sensitive) can be found referenced in your page?
