You can create a more advanced format using html. In the first text field you need to set the TextFormat property as crHTMLText. In this case, the text field will interpret html after assignment in the formula, you can put the following
if {?PARAMETER}=3 then If not IsNull ({TABLE.FIELD1}) Then "<p><b><font color='#00559c'>" & {TABLE2.FIELD1} & "</font></b></p>" & {TABLE2.FIELD2} & ": " & {TABLE2.FIELD2} Else "<p><b><font color='#00559c'>" & {TABLE2.FIELD1} & "</font></b></p>"
