Adobeform - Change the color of a cell based on condition in formcalc

Hello Expert,

I have a requirement which needs to change the color a cell based on a condition.

I have tried some codes found on the net but none is working.

I have also tried this code : but this is not also working.

if (  data.Mainpage.Table_consignation.cnsign_rslt_essaie.grpe_des_taches.titre_princ_grp_tache.Bodyrow.descr_grp_taches.descrp_taches.Rangée1.ZSAISIR_MA_15.rawValue == 'X' )

then

data.Mainpage.Table_consignation.cnsign_rslt_essaie.grpe_des_taches.titre_princ_grp_tache.Bodyrow.descr_grp_taches.descrp_taches.Rangée1.ZSAISIR_MA_15.fillColor = '200,10,10'

endif

Can you please help?

Thanks.
