[mapserver-users] Attribute based symbol

[Adam Eskreis]

It doesn't seem to be working for me

I get the following error from apache:

 [MapServer Error]: msAddImageSymbol(): Error opening image file
/var/www/htdocs/maps/[symbol].

I am using the symbol as:

SYMBOL "[symbol]"

I also tried

SYMBOL [symbol]

neitehr works

Is this only possible with mapserver 5? I believe I am using 4.10

Thank you

-Adam
