Ah, clearer now. In order to pass the AFF= name/value pair through the RewriteRule where you are passing the VAR1 and VAR2 parameters to /index.php, you will need to use the [QSA] --Query String Append-- flag on the rule. Otherwise, your VAR1/VAR2 parameters will replace the original AFF= query by default.

Merging [QSA] with your existing flag, use [QSA,L].
