create text file in OS X

i know i’m missing something simple here… when trying to create a text file’s content yesterday, i got this message:

this code made the file but apparently couldn’t write to it:

set theFile to (make new file at theLoc with properties {name:"blah_log.txt", kind:"file", creator type:"ttxt", owner:"nate", owner privileges:"read write"})

what am i missing? and do i need to include privilege info in the properties?
