Flatten[list, n] flattens to level \ n. Flatten[list, n, h] flattens subexpressions with head h." ?FlattenAt "FlattenAt[list, n] flattens out a sublist that appears as the nth element of \ list. If n is negative, the position is counted from the end. FlattenAt[expr, \ {i, j, ... }] flattens out the part of expr at position {i, j, ... }. \ FlattenAt[expr, {{i1, j1, ... }, {i2, j2, ... }, ... }] flattens out parts of \ expr at several positions." I don't know the structure of Your list and the structure You want but one of the functions may help Jens
