    Hi,
      I have recently installed FLASH 2.2 and run the basic sedov problem
      with all default settings. Then I built the HDF5 wrappers for the
      IDL routines in fidlr2 and ran xflash, following directions on
      pages 6-8 of the user's quide. I get some IDL errors, copied
      below. Can you help me resolve this problem?
      
      Thanks,
      Jason Tumlinson

      System is Linux 2.4.18, mpich-1.4.2, ifc compilers, HDF5, IDL 5.5
       
       
    Here's the error message:

    Here's the relevant passage of merge_amr.pro (lines near 573).

                    yindex LE (yrange_max_index-yrange_min_index)) then begin

    ; store it
                    temp_merge[xindex:xindex+xspan, $
                               yindex:yindex+yspan] = $
                      sub_array[xstart:xstart+xspan, $
                                ystart:ystart+yspan]

                endif
            end
