WPA - Help with rules?

Hey everyone,

I've just started using oclhascat, awesome tool, pretty simple to get up and running, but I'm having a little trouble configuring rules.

I've trimmed down a wordlist so that it only contains words between 8-12 letters long, all lower case, I'd like to add a rule that will rotate the first letter upper and lower case, and would add/try a combination of all numbers in the range 1-9999 to the end of the word

password1-password9999
Password1-Password9999

After some reading I tried this:

oclHashcat64.exe -m 2500 WPA.hccap -c wordlist.lst ?d?d?d?d

But it it gives the error: ?d?d?d?d: No such file or directory.

Any help would be appreciated.

Thanks,
Dave
