Oh, This can not stand!
Ok, last time I looked, "grammer" was spelled "grammar". You need a comma after that word no matter how you spell it. The next sentence is a run-on that *could* be salvaged with a semi-colon (this one ";") after the word "replies". You also use it's (it is) where you mean "its". Pot, kettle, black. (Idiom, not intended to be a complete sentence.)
