Thank you for your post.
The script step "Save Records as Excel" is unavailable under iOS. When editing the script, change the pop-up below "Show Compatibility" in the bottom left corner to "iOS", and this will show you all available script steps available. Notice that "Save Records as Excel" is grayed out.
Due to Sandboxing under iOS, FileMaker Pro cannot export to a different work area (including Dropbox). You can only export to the current work area. Instead, use Get ( DocumentsPath ) to save and access files.
Since Excel can also import other file types, you may want to consider using comma-delimited or tab-delimited text files.
Let me know if you need additional clarification.
One possible work around, though I stress that the way the you work with your database may make this an option that doesn't work for you:
If you use FileMaker Pro to insert the excel file into a container field, FileMaker GO users should then be able to export that copy from the field and send it as an attachment.
I'm not using the "Save Records as Excel" script step at all; the excel file in question does not contain records exported from FMP. It's simply a file. I do not need FMP to access the content of the file (via exporting or importing). I only need FMP (and FM Go) to find the file and attach it to an email.
I'll tinker around with Get(DocumentsPath) in iOS and see what happens. It's not clear where I would store an excel file in iOS, admittedly, but let's see what FM Go does. Would it work if I stored the file in a container field, then exported it as part of the script only to set the $Filepath?
If you aren't accessing the file from within FileMaker Go, then make sure the Excel file is in the same work area as FileMaker Go. Otherwise, FileMaker Go would be unable to access it.
The suggestion from PhilModJunk is excellent, as the Excel file would be contained in the database file. Another option is to connect your iOS device to the desktop computer, launch iTunes, and copy the Excel file into the FileMaker Go work area. From there, you can then email the file.
