Search in a Matrix

Hello my friends.

I hope you can help me here.

I have an excel with a matrix like the following

	      Abrantes	     Amiais 	       Benavente	Chamusca	      Constância
Abrantes 		                58	             98	    40	                   14
Alcanede 	66	                12	             67	    54         	   50
Alcanena 	46	                10	             72	    32	                   36
Almeirim 	66	                38	             34	    24	                   60

In this matrix you have the "origin city" as rows on the left, the "destination city" as columns , and the values.

What I need to do is, given a origin city and a destination city, the macro must read the value.

Anyone can help me how to achieve this ?

Thank you in advance,
