in Script if condition executing two times

Hi In Script,

The IF condition is executing two time. if it executes one time then the result is correct. if it executes two times then one more field gets printed which is not required. the code is as shown below

/:      IF &G_ISTEXT& = ' '
DT   ,,,,&HKOMVD-VTEXT&,,
/:      ELSE
/:      INCLUDE &G_VTEXT& OBJECT TEXT ID ST LANGUAGE &GW_SALES-LANGU&
/:     ENDIF

Should i need to clear the work area, Please let me know the solution for it.

Actually it has to execute one time only, but it is executing two times.

Regards,

Kumar
