I am relatively new to PHP. But something I can't seem to make work is when I call one of the functions I have made and a variable is set inside that function.... eg. function blah ($bl,$ah) { $bl++; $ah++; $blah=$bl+$ah; } I then echo $blah; somewhere else in the script but nothing is echo'd. How do I make it so that I can use $blah anywhere in the script? Thank you in advance for any help. ------------------------ Nathan Croker
