getBytesTotal for loadVariables?

Hi there, my first post.

I’m doing my portfolio in FlashMX using Actionscript. Everything in that sites has a preloader.

Anyway, in the actual portfolio section I use variables form a .txt to load each work (that way I can add in a more easy way new content). The .txt contains location of images, text shown, titel, and some other variables. Each .txt is aprox. 350bytes.

The problem is that if the variables aren’t loaded fast enough the content of each work is shown wrong.

Is there a way to calculate getBytesTotal() for variables ?
