Hello, I want a formula that counts same String from a column against the rows. : Site ID	Node
LLR580	PF
LLR580	MW
LLR580	Fiber
LLR580	PTCL
LLR581	PF
LLR582	PF
LLR583	MW
LLR581	MW
LLR582	PF
LLR580	PF

When i enter LLR580 in a column it should return:  2PF,1MW,1Fiber,1PTCL  in next column of it.

Siteid  Node
LLR580  2PF,1MW,1Fiber,1PTCL

And so on.

TIA
