SAP Script Data not appearning

HI all,

I am new to SAP Script.

In a script I have declared variable in the driver program.

Also getting value in it. But the problem is the value is not appearing in the preview.

I declared that varia in script also. As DEFINE &GV_CIN& = &T001Z-PAVAL&.

Still I am getting the output..

Is there anything that is missing?
