Hi ...,

Your scripts looks correct, but you got some small mistakes in your script, which might make it fail. I also think your could improve your scripting style to make it more readable, which will help you to avoid mistakes. You set the defaultFolder for no apparent reason. References to card fields are a relic from the HyperCard days and I can't imagine you need that for iOS apps.

The tendency of programmers to use non-human-like language for object names really drives me more than nuts. LiveCode allows for spaces in object and file names. Use them!

-- write
put specialFolderPath("documents") & "/Defaults" into myPath
// I don't know whether you need the next line, just let's be sure it exists
if not (there is a folder myPath) then create folder myPath
// mind that LiveCode allows for readable object names.
// The same applies to files names. Use spaces!!!
put myPath & slash & "Students Group" && the hilitedLines of fld "Group Theme Titles" into myFile
open file myFile for write
write fld "Students" to file myFile
close file myFile

The read script is almost the same, using read from instead of write to. Note that I'm not using the defaultFolder because there is no need for it.
