function defining including solve command

bonjour

I am very sad because the code which I am trying now cannot
work. I wrote a function, the definition of which includes
"solve" command. If simplified, this is as follows.

Fn[x_,y_] := Module[{formulae},formulae=........, solution=Solve
[formulae==0,K];.........;solution[[1]]]

If I do not use the loop structure (for example, Table etc),
it works. But, if this function is located inside the loop,
for example,

y = 7;
Do[Table[N[Fn[x,y],{x,1,3,0.1}]],{i,4}];   (* Bang!!! *)

Always execution of such kind of loop produces an error message,
like "imcomplete! It needs more input". How should I do in such
case? MapThread command? If one writes the code with the
same content without using Function (:=) only with Assignment
(=), one can successfully rotate the loop. 

regards best.
