demo.recorddemo not working

[Gadfly Jr]

im trying to film myself in a local game,, but when i type demo.recorddemo in the ~ thing,, this is what pops up:
Error: Too few arguments, the min no of arguments is 1!

what does that mean lol?

how can i fix the problem so i can record demos in my local games?
thanks :)

EDIT- btw this is in Sandbox 0.21

You need to add a name on the end of that.
min no of arguments means you need to name it something of at least 1 character.
Like "demo.recorddemo 1" - would make a demo file called "1.bf2demo"
