Reshape Wide Long Command giving error 498

[Erin McKie]

Hi

I am trying to convert a wide-format data set into a long-format. The data are organized as shown below. When I type in the following command "reshape long sch, i(Period) j(school)" I receive this message:

variable _j contains all missing values
r(498);

Any thoughts on how to correct?
