Photoshop script (textItem.width)

I am very new to scripting and I am having a little difficulty retrieving an accurate width for my text.

My code:

var widthx = artLayerRef.textItem.width.value;
var w = (227 + ((border-1)*687)) + ((605-widthx)/2);

widthx is passed to a function I named GetDim(widthx...etc) which contains the second statement (var w= 227......)

The width that I get isn't the actual pixel width of the text (I measured it in photoshop). If anybody can help it would be deeply appreciated.

Thank you.

What language are you coding in and what is it for? Hard to be of any help with just a snippet of code.

I'm coding in Javascript. My question basically boilds down to, why doesnt artLayerRef.textItem.width.value return the actual width of the text content?
