[FX.php List] How to use SetFMGlobal

[malcolm at notyourhomework.net]

Let me describe what I want to do, perhaps there is a better method. 

I want to pass data from the web to the script. There are two items, a postcode which is used as the basis for search and a number which is the distance to extend the search range. 

1. user provides postcode and optional extra distance
2. On the filemaker side. 
	1. Search by postcode
	2. If the option "extend by distance" is present then set the global field to that value and run a script, which uses the global to perform a find which extends the range, and possibly the found set
	4. return records

The thing that I want to achieve is pass transitory data from the web to FMP. I have no interest in the global persisting.

Whenever I include SetFMGlobal I don't get a result. If I comment out the line I do get a result, though my script returns the wrong set because the global is empty.
