Annoying error!

Argh..this is stupid! All I'm trying to do is print out the readme for a plugin...I'm getting this error;

A fatal error has occured:

Quote:

Can't use string ("28461") as a SCALAR ref while "strict refs" in use at /usr/local/psa/home/vhosts/ace-host.com/httpdocs/dumps/admin/Plugins/Duplicate_Check.pm line 63.

Please enable debugging in setup for more details.

The HTML I am using looks ok to me...all the @'s are escaped, and the Perl checker does not return any problems. Does anyone know what may cause this problem? If you need to see the sub, please let me know, and I'll paste it over for ya Smile

Cheers

Seeing the code would help.

Its mainly HTML, so I can't see why it won't work!

It is;

Code:
sub readme { 
# ------------------------------------------------------------------- 
# This subroutine will get called whenever the user clicks 
# on 'Readme' in the admin menu. Remember, you need to print 
# your own content-type headers; you should use  
# 
   print $IN->header(); 
# 

print qq| 

<html> 

<head> 
</head> 

<body> 

<p align="center"><b><font face="Verdana">Duplicate_Check</font></b></p> 
<p align="center"><font face="Verdana" size="2">There is nothing really needed  
here. All that will happen, is that if a link has been submitted already, the  
user will get an error, and the link will not be added again. Pretty simple :)  
No changes are needed from the user/admin end. If you like this plugin, please  
consider sending me a little $$$'s from 
<a target="_blank" href="http://www.ace-installer.com/pay.php"> 
http://www.ace-installerk.com/pay.php</a>.</font></p>

</body> 

</html> 


|; 

}

If I just replace that with;

Code:
sub readme { 
# ------------------------------------------------------------------- 
# This subroutine will get called whenever the user clicks 
# on 'Readme' in the admin menu. Remember, you need to print 
# your own content-type headers; you should use  
# 
   print $IN->header(); 

print "test"; 

}

Then it works fine, and prints "test" Unsure

$$$

$$ is the scripts process ID, $$var is a scalar reference, hence $$$ makes perl think you are trying to print out the process id as a scalar reference.

Escape the dollar signs or simply use q| | instead of qq| | then you don't need to escape them, including @
