sc_field_style in grid summary

Can anyone tell me how to use sc_field_style in the grid summary. I figured out how to calculate the percentages on the fly in the summary, but now I need to change the color of the field based on its value after it calculates the percentages.

I’ve tried the following:


sc_field_style({field}, "#FFFF00", "","","","","bold");
sc_field_style({sum_field}, "#FFFF00", "","","","","bold");
sc_field_style({sum_quebra_field}, "#FFFF00", "","","","","bold");
sc_field_style({sum_groupby_field}, "#FFFF00", "","","","","bold");
