Can you post an example of the calculation you are sending to send event? What are you doing in preparation to verify that the file path you are passing exists?
Hi - in trying to explain it to you we came up with the solution, we were trying to tell it the file path and have the file name as well as a variable, rather than joining path and filename and using as one variable - if that makes sense
filemac:/Studio Raid/Image Library/Filemaker storage/$FN - did not work
set variable [$FN;value: Image::full name with path]
$FN - worked
