GUI scripting question -am I sunk?

Question

Hi all,
I am working on an Applescript to bring up two different non-Applescript-able applications (ie. ones w/o a dictionary) and am getting the error:
NSReceiverEvaluationScriptError : 4 from Applescript.
I have "Enable access for assitive devices" checked in SystemPreferences and am GUI scripting.
Here's the snippet of code that gives the error:
tell application "System Events"
if UI elements enabled then
activate application "TRx Recorder"
tell button " Record " of tool bar 1 of window "TRx Recorder"
click
end tell
end if
end tell
I generated the code "tell button ..." from the Prefab's UI Browser.
I've tried clicking via the name of the button, and via the position of the button. Same error.
Does this mean I'm sunk and can't get the app to respond to my Applescript?
When I select the Action of button " Record " from within the UI Browser, it works fine.
What am I doing wrong?
Thanks!
Ed

Hi Camelot,
Yes indeed I needed a "tell process ..." block, as well as, 2 extra spaces in the label for the Record button.
I got the following to work:
tell application "System Events"
if UI elements enabled then
activate application "TRx Recorder"
tell process "TRx Recorder"
click button " Record " of tool bar 1 of window "TRx Recorder"
end tell
end if
end tell
I dug around using UI Browser and discovered that I needed 2 blanks in front of and 2 blanks behind of the label "Record" to correctly access the button. I originally had 1 space in front of Record and 1 space after Record within the quotes. With only 1 space I get the Applescript error I mentioned. With 2 I don't get the error.
Many thanks for the tip, it made me look closer at the labels of the buttons in UI Browser.
