i need something that
$IfSameReplace(x,y,o)
for example
$IfSameReplace(%genre%,rock,1)
$IfSameReplace(%genre%,metal,2)
$IfSameReplace(%genre%,alternative,3)

if value of %genre% is the same with value "rock" then must displayed value "1",
if not,then should not output it,but if %genre% is the same with "metal" then should display "2"
how is possibly to realize it?
Thank you very much!
