Breve Screensaver creature code problem

Hello,

When i copy the breve screensaver creature file (creatures.tz) into my demos folder and bring over the classes I get the following error.

Error at line 138 of "creatures.tz":

expected type "list" or "hash" in lookup expression

Looking at the code it show the following, i will highlight line 138 with a *>:

mindist = 10000.

foreach link in all Links: {
if | ( link get-location ) - link{ "_startLocation" } | < mindist:
mindist = | ( link get-location ) - link{ "_startLocation" } |.
*> }

return mindist.

Now if I take out some of the code to leave,

mindist = 10000.

return mindist.

it works, but obviously the min dist doesn't work.

Can anyone help?
