Module Pool Selection Screen not working

Hi All,

I am making a module pool program in which I have to add a selection screen.

But when I add the code of it system gives an error

"SELECTION-SCREEN statements can only be used between SELECTION-SCREEN BEGIN and END OF SCREEN (program type is not "1"). ."

I know that this is not a program of type 1.

The same thing I saw in different client they have done the same thing and it is working.

SELECTION-SCREEN: BEGIN OF BLOCK b1 WITH FRAME TITLE text-001.

select-options :s_ebeln for ekko-ebeln no intervals.

SELECTION-SCREEN: END OF BLOCK b1.
