question about decirselo

Question

my friend said "no estare en clase hoy, puedes decir carmen y Gloria. she was corrected to "decirselo a...". I think i understand why the statement was wrong but i'm not sure. My understanding of the grammar is:

decir: to tell

le: them

lo: them

but isn't there a rule that says the when le and lo are used together it becomes se lo??

therefore "decir+se+lo" = tell it to them

Is my understanding correct? what are the rules for understanding the correct usage of this?
