Arggggh. put Google maps URL weirdness

[Gerry]

This works:

put url "http://maps.google.com/maps/api/staticmap?center=canberra&zoom=8&size=512x512&maptype=roadmap&sensor=false" into someimage
put someimage into image 1



But when I use the text in a field in building the url it breaks - I get a "bad request 400 error" from the Google server:

put url "http://maps.google.com/maps/api/staticmap?center=" & fld "place" & "&zoom=8&size=512x512&maptype=roadmap&sensor=false" into someimage
put someimage into image 1

What am I missing? When I write the string out to the message box and then paste that into the url field in my browser, it works fine.

Argggh.
