i try rejoinders put in to if/else..

is it wrong?

Rejoinders are independent rules (hence they are not put inside of if/else, nor did you).
But $$variables ONLY have meaning during the current volley. They are not preserved across volleys. Only single dollar variables are.  So a rejoinder like this:
a:(~no)your product is ^join($$product2 ?)

will NOT have $$product2 defined. Would have to be $product2

I appreciate your support.
