[Wien] QTL-B Error

[محمد ارشد فرحان]

 Dear stefaan,i checked my case.in1c file, it does not have any other line for L=2.  
.     .     ..     .     .  0.30    4  0      (GLOBAL E-PARAMETER WITH n OTHER CHOICES, global APW/LAPW) 1    0.30      0.000 CONT 1 1   -3.20      0.001 STOP 1 2    0.30      0.005 CONT 1 0    0.30      0.000 CONT 1  0.30    4  0      (GLOBAL E-PARAMETER WITH n OTHER CHOICES, global APW/LAPW) 1    0.30      0.000 CONT 1 1   -3.20      0.001 STOP 1 2    0.30      0.005 CONT 1 0    0.30      0.000 CONT 1.     .     ..     .     .
also the output file case.scf1up has it:
          ATOMIC SPHERE DEPENDENT PARAMETERS FOR ATOM  Mn3:e__0007: OVERALL ENERGY PARAMETER IS    0.3000          OVERALL BASIS SET ON ATOM IS LAPW:E1_0007: E( 1)=    0.3000             APW+lo:E1_0007: E( 1)=   -3.2885   E(BOTTOM)=   -3.322   E(TOP)=   -3.255             LOCAL ORBITAL:E2_0007: E( 2)=    0.1875   E(BOTTOM)=   -0.035   E(TOP)=    0.410             APW+lo:E0_0007: E( 0)=    0.3000             APW+lo
hope you can guide me further.Regards,M. Arshad Farhan
