Programming of remotes using a jumper on pins 4 & 8.

(1999 Chevrolet Astro)
It will allow me program any one of my three remotes, but when I try to program a second remote, it will not work. I am at a loss as to why I can't program my other remotes.

if it worked on the first remote,it should work on the other two.that one is easy,just don't remove the jumper until all remotes are programmed.pin 4 and pin 8,jumper HAS to be connected very good.once you program the first one,you have to program the next two within one minute.also all remotes must be present to do this.how are you programming them?step by step?
