Saving from Quark


after I use this statement:

save document 1 in file (“Art Department: Work Files:” & destFolder & “:” & jobNum & “proof”)

my document is correctly saved. then if I hit “cmd-s” is works as if i have hit “save as” instead.
Does my save statement above need an additional parameter for quark to understand that in the future,
I just want to save in the file in the same destination?
