I am trying to capture an ERROR when I run this script in FMP 8.5:
tell application "Printer Setup Utility"
try
set the current printer to printer "Officejet 6200 series"
on error errMsg number errNum
end try
quit
end tell
set field "gERROR" of table "Computers" to errMsg
When I MISPELL the printer name, the script run to completion and
spits the
error in my FMP fields called "gERROR".
When I spell the printer name CORRECTLY, the script generates AS
errors
saying the errMsg was not declared (also an error number). What do
I need
to change to get it to run to completion in both scenarios?
The error handler is entered only when an error occurs within the try
statement, Don. So if there's no error, the handler is skipped - and
the variables errMsg and errNum are never defined.
One way around this would be to move the statement that sets the
field in FMP to within the error handler.
However, to avoid including the statement in the 'tell application
Printer Setup Utility' block, I'd suggest you try switching the
nesting of the tell and try statements - something like this:
-----------
try
tell application "Printer Setup Utility"
set the current printer to printer "Officejet 6200 series"
end tell
on error errMsg
set field "gERROR" of table "Computers" to errMsg
end try
-----------
