Issue - SI(CHERCHE)

Dear all,

I am having an issue in an excel file regarding the function IF(SEARCH).
I need to use three of the fuctions in the same cell, but it only works for the first line.

Here is the function :

=SI(CHERCHE("JULIAN";A3);0,4;
SI(CHERCHE("LADY";A3);0,7;
SI(CHERCHE("LESLIE";A3);0,9)))

SI  = IF and CHERCHE = SEARCH in French.

Thank you for your help.
