Exception color with formula variable(replacement path)

Hello,

I tried to define exceptions in a query which "from" and "to" values

are determined by formula variables with replacement path. I checked

the values of the formula variables and they are right. <b>But <b>the cells

are not colored</b></b>. When I set the same values in the field "from" and "to" without variables : the colors appear.

Could help me to resolve this problem please ?
