This is what i have:

NewModel		Traded_Model	table1
Expedition		2.3CL			1
Montero_Sport	2.3CL			1
200SX			200SX			1
4Runner		200SX			1
626				200SX			2
Accord			200SX			2
Alero			200SX			1
....				...				...

where "table1" are the frequencies

This is what i want:

				2.3 CL		200SX	.....

Expedition		1			1
Mondeo Sport	1
200SX			0			1

......

I tried the following:

reshape wide table1, i(Traded_Model) j(NewModel) string

Then i get the error message Table12.3CL invalid name. Any suggestions where i am wrong?
