Mad...how can it exist, yet it doesnt?

This is silly....this code;

Code:
   if (!$found) {  
        if ($debug) { &debug("Wasn't found, so adding $into_cron  $query"); }  
        if ($debug) { &debug("\$query = $query"); }  
        if ($debug) { &debug("\$into = $into"); }  
        $back_into_file .= "$into $query\n";  
   }

Produces;

DEBUG INFO: $query = INSERT INTO
DEBUG INFO: $into = test1234

YET, viewing the contents of $back_into_file shows;

INSERT INTO

...i.e without the $into part! How can the variable exists one line above, but not show on the next? It silly!

Any ideas? Crazy

Well firstly why are you using three "if" blocks?....all those debugging calls could go inside one "if" block as they are all checking for the same scalar - $debug

As for the other thing - shouldn't the order be INSERT INTO test1234?....in which case it should be $query $into not $into $query

As for it not showing $into, there's no reason why, it must be an error somewhere.

Are the variables getting reset in &debug() ?

That debugging stuff is only there as a temp, but I'll make it one statement if it keeps you happy Wink

Code:
   if (!$found) {  
        if ($debug) { &debug("Wasn't found, so adding $into_cron  $query"); 
                      &debug("\$query = $query"); 
                      &debug("\$into_cron = $into_cron"); }  
        $back_into_file .= $into_cron . " test\n";  
   }

the degbug sub is;

Code:
sub debug { 
# ------------------------------------------------------------------- 
# This is where we show debug info...no Exit command here though... 

my $show_it = shift; 
print $IN->header(); 
print "<font color=purple><b>DEBUG INFO:</b></font> <font color=red>$show_it</font><BR>"; 

}

Its stupid, cos the only variable I create in $debug is $show_it Unsure

I'm wondering if it would make a difference that $into_cron is made from within an 'if' statement? Sounds silly, but you never know Tongue

Thanks for the replys so far....

Never mind, I fixed it....where $into_cron was being defined in the 'if' statement, I was also assigning the \n to it....but when I tried to add it, there was another zn being added....thus it was doing;

$into_cron
test

Well, thats fixed now..thanks for the help guys Smile
