You don't show us what is in your loop but I suspect you are trying to change a named structure, which is forbidden.

For example, if you create a structure and name it 'ksom'

create_struct,ca,'ksom',['DATA','XC','YC','DX','DY','TIME'], 'd(767,684),d(1),d(1),d(1),d(1),a(1)'
ksom=replicate(ca,6)

then you cannot later define a structure named 'ksom' with a different sized array.

IDL> create_struct,ca,'ksom',['DATA','XC','YC','DX','DY','TIME'], 'd(245,839),d(1),d(1),d(1),d(1),d(1)'
% Conflicting data structures: <DOUBLE Array[767, 884]>,KSOM.

I suspect you want to use an anonymous structure (use '' instead of 'ksom' ) though you could also use a different name each time the structure definition changes.

(Note that the procedure CREATE_STRUCT is not native to IDL
http://idlastro.gsfc.nasa.gov/ftp/pro/structure/create_struc t.pro
though the *function* CREATE_STRUCT() is. ) --Wayne
