When register globals is ON (what we do), if you pass a variable named $foo to a PHp script you can directly access it by doing: echo "the value of foo is $foo"; When register globals is OFF, you need to extract it from an array that is created to store the variables: echo "the value of foo is " . $_GET['foo']; The difference is minor, but if you do not take the latter route, in an environment where register globals is off, your variables will never have values. This is pretty much irrelevant, as I have written the latter approach (which works regardless of the value of register globals) into the Feed2JS script but had not done so for the build.php one which can be used locally to create a form that allows users to preview the Feed or create the cut and paste javascript. It is not required to use the Feed2JS scripts (but helps as a tool). Bottom line- you do not really need to worry about it.

echo “the value of foo is $foo”;

When register globals is OFF, you need to extract it from an array that is created to store the variables:

echo “the value of foo is ” . $_GET['foo'];

I am not a coder, so I did a little searching on the net and found the folowing that has fixed the problems for your original build script: <a href="http://www.liquidpulse.net/code/3">http://www.liquidpulse.net/code/3</a> Both suggested methods workd for me. I will have to go ahead an install your latest version as well. Thanks for the very valuable work on this.
