Put the summary of the bug you're having here
Any command code with the : symbol is not working like the horse spawn egg is not working. And I did make sure that the command code function( LAN or whatever) was on. the command for this was give tab( the tap puts in my screen name in) 383:100 #( was how many I wanted). I have tried this on more than one computer.

What I expected to happen was...:
Describe what you thought should happen here
It should have given me the yellowish colored spawn egg that I could put down and spawn a horse to me after I put in the command code in.

What actually happened was...:
Describe what happened here
What happened was it told me that this code was not a working code or something like that.

Steps to Reproduce:
1. Go into the minecraft game
2. once in the game itself push the F1 button which should bring the pause menu. and a help page of sorts. just close that page so you're still on the minecraft game
3. click on, "open to LAN"
4. click on, "allow cheats" so it says on.
5. then click on, "start LAN world. It should say "local game hosted on ______" the under line meaning the number that follows on.
6.push the / button so a chat bar like bar appears with a / in it.
7. type in the following sentence without removing the /, keep it in the bar. give (then push tab, this will put in your screen name.) 383:100 #( replace the # with a number under 65.) put a space in between each word. For example your screen name is black ninja and you wanted 10 horse spawn eggs. you'd put, "/give black ninja 383:100 10" in.
8. then hit enter
9. this will bring up a message in red saying, "383:100 is not a valid number.
