Inaccurate awk response
can someone help me figure out what's wrong with this awk code?

Code:
awk '/CRON/ && /./ {i++;} { if((i>=4) && (i<8)) {print | "TIMO=$(date +%s) ; TIMO2=$(uname;who) ; echo $TIMO ---- 1 ---- Yes_Recoded,$TIMO2 ---- i >> /tmp/gona.txt" }
 else if (i>=8) {print | "TIMO=$(date +%s) ; TIMO2=$(uname;who) ; echo $TIMO ---- 2 ---- Yes_Recoded,$TIMO2 ---- i >> /tmp/gona.txt"} } {i++;} 
END { if(i<4) {print | "TIMO=$(date +%s) ; echo $TIMO ---- 0 ---- No_Recoded ---- i >> /tmp/gona.txt" } }' /var/log/syslog

first of all, it appears two conditions are being met at once as I'm getting responses for both Warning and Critical ( 1 and 2 ).

after each condition is met, i want to see the value of "i". but the output i get is just the letter i, without its value:

Code:
1396193620 ---- 1 ---- Yes_Recoded,Linux jserver tty7 2014-03-28 01:44 (:0) jserver pts/3 2014-03-28 01:44 (:0) jserver pts/4 2014-03-28 01:45 (:0) jserver pts/0 2014-03-28 01:48 (:0) ---- i

A few comments:
- How do you see two conditions are met? There's only one output line in your sample.
- && /./ will be TRUE for any non-empty line, as . matches any char.
- The "i" you refer to is an awk- variable, but your file is written from a (sub-) shell, where "i" is not defined (were it, it needed a $ sign for evaluation). Plus, awk's print is lost - you're not reading stdin anywhere in the shell.
- formatting/indenting the awk- script nicely will make it way more readable and understandable!
