Unmatched [ in regex; marked by <-- HERE in m/
    ^
    (?: [ <-- HERE A-Za-z0-9+/ at C:\aaa\aeh_pop.pl line 153.

I thought I was getting a problem with the regex...not the IF....but I didn't copy this in because i figured it was something I was doing. I see matched brackets... I tried to pull up into one line thinking the white space was giving issues...that didn't help. Thanks.
