I'll help you with that Klitschkofan.

Take the url from youtube

http://www.youtube.com/watch?v=e5uPaNxcq7w

Then place the part after the = sign in between the youtube columns

taking this

e5uPaNxcq7w

Place it in between this

[ y o u t u b e = 4 2 5 , 3 5 0 ] [ / y o u t u b e ]

No spaces ok.

so take this

e5uPaNxcq7w

between this

[ y o u t u b e = 4 2 5 , 3 5 0 ] [ / y o u t u b e ]

Looks like

[ y o u t u b e = 4 2 5 , 3 5 0 ] e5uPaNxcq7w [ / y o u t u b e ]

Get rid of the spaces, and you get this

[youtube=425,350]e5uPaNxcq7w[/youtube]

That should help.
