script_add_str problem.

The word Shown in error is nowhere in the file mentioned.[code=auto:0] Posted 18 November 2013 - 01:02 PM I have one more error in which filename is shown properly but wrong Variable [Warning]: script_add_str: detected possible use of wrong case in a script. Foun d 'Coal', probably meant to be 'coal' (in 'npc/Restock.txt'). If it is a local (.@) variable, and you're absol utely sure you used the correct case, please disragard this message, otherwise p lease correct your scripts, as this will become fatal in a near future. But that file does not contain any word/variable like "coal".[/code]
Any Fix for this? Still there's post which contain this false post info.

The actual problem is FileName is not been shown properly.
