Umbraco outputting filesize - umbraco

Question

I'm trying to output the correct size for pdf files that has been uploaded.
But the only output is 0 - what am I doing wrong?

Alright, I've move the size variable into the for-each loop, as it varies per file and fixed a few typos:

That should do the trick.
