Variable not responding?

[Goldtoise_Gaming]

I have been preparing my super mario maker based stream,and I got everything except one little thing done. I was trying to make a command that will submit user levels plus show the name of the level and the difficulty. Here is the response for it:

$(User) has submitted his/her Mario Maker level! $(urlfetch http://www.pokemonrby.com/smm/submitlevel.php?courseid=$(1)&twitchusername=$(user)&channel=[Channel]&secret=[APIKey])Wait a minute before submitting another level.

when it gets called, it says that $(User) is not a valid variable. I double checked on the variables page, and it is. Could someone please tell me what I need to fix?

Variables are case sensitive. Make sure you are using $(user) and not $(User)

Thanks for the reply! I changed to another method of getting level codes, but thanks anyway!
