hello, i have a grid with format in the header (fontbold, an specific width, tahoma,etc.) but when i select an option button it change all, specially the width of the columns, this is my code:

IF thisform.optiongroup1.option6.value=0 then
   DO QPRZONA.QPR
  else
   DO QPRCOMM.QPR 
ENDIF   

thisform.grid1.recordsource="ZONAS"
thisform.grid1.refresh
THISFORM.GRID1.COLUMN1.WIDTH=75
THISFORM.GRID1.COLUMN3.WIDTH=75
THISFORM.GRID1.COLUMN4.WIDTH=100

I think is for the alias, but how can i fix this?
