variable expansion of check item in users file

Hello, I have several accounts stored in users files for which i have set set the Pool-Name controll attribute based on the Huntgoup-Name. So i tried something like this: account1 Cleartext-Password := "passwd1", Pool-Name := "%{Huntgroup-Name}_suffix" Unfortunatly the expansion of the variable doesn't happen and all i get is '=25=7BHuntgroup-Name=7D_suffix' If i put exactly the same thing in the reply item expansion is done correctly... account1 Cleartext-Password := "passwd1" IP-Address-Pool-Name := "%{Huntgroup-Name}_suffix" Is it a normal behaviour? How else can I achieve it (I would appreciate not to duplicate users entries for each of my huntgroup!)?
