I am getting an invalid expression on a custom percent field with this formula. Any suggestions CASE WHEN (({custbody17}-{custbody_mnt_tot_cost_so})/{custbody17} < 0.0) THEN '<div style="; background-color:yellow; colorblack;font weightbold">' ||{custbody17}-{custbody_mnt_tot_cost_so}/{custbody17}|| '</div>'ELSE'<div style="background-color:red; colorwhite;font weightbold">' || '10' || '</div>'END
