Adding 4 digit variable number to Name wordlist

[mohsen95]

I have a wordlist of names and I want to add [4-digit-year] to end of each password using rule or maskprocessor:
abcd [abcd?d?d?d?d] =>abcd1965, abcd2015, abcd1722 ... and so on
I added a rule to the string:

Code:

-r /rules/year.rule

And inside of the rule file I added:

Code:

$?d $?d $?d $?d

but it didn't work! i realized it adds a "?" to the end of names and use "d" to duplicate that [4 times].
the results was like this:
abcd?abcd?abcd?abcd?abcd

please help.

Full string:

Code:

-m2500 -a0 hccapx/wifi_test.hccapx dics/names.lst -r rules/add_year.rule
