There are issues with your code. The code below works, assuming the logic you are specifying is want you want. The only statement that is not a valid statement is the << Justify Text("center"). It is only valid when referring to a display window text box. The other errors are just improper references:
For( ii = 4, ii < 6, ii++,
Column( summary_executive_RNG_alignment, orignal_columns0[ii] ) << Format( "Percent", 10, 1 );
//<<justify text( "center" );
For( RowNum = 1, RowNum <= N Rows( summary_executive_RNG_alignment ), RowNum++,
If( 0 < Column( summary_executive_RNG_alignment, orignal_columns0[ii] )[RowNum] <= 0.6,
Column( summary_executive_RNG_alignment, orignal_columns0[ii] ) << color cells( "RED", RowNum ),
If( 0.6 < Column( summary_executive_RNG_alignment, ii )[RowNum] <= 0.9,
Column( summary_executive_RNG_alignment, orignal_columns0[ii] ) << color cells( "Blue", RowNum ),
Column( summary_executive_RNG_alignment, orignal_columns0[ii] ) << color cells( "GREEN", RowNum )
)
)
);
);
