It worked but there is one problem...
The debugg list says there is a error with my video_mode?

// test9.wdl
var video_mode = 7; //revolutie
var video_depth = 16; //bit

function main()
{
level_load("test9.wmb");
wait(2);
}

error: syntax error: can't convert GETPVALUE:FIXED:FIXED
<var mode = video_mode;>

I think its something small but I cant find it xD
