Matlab switch-case issue - matlab

Question

I got a strange issue when i try to run a multiple switch-case ( 6 concatened switch-case, from 2 to 11 choices, char choices).
the inputs for the m. file with the swith case come from a GUI with 6 buttongroup and radiobutton, but i guess this is not the problem.
In fact, the problem is that if i pass the values "manually", kinda:
evaluation= Holdem_Postflop_Decision_Tree('midv','rn','fd', 'oop', 'hu',25)
i got to the right solution, that is simply a string ( ideally, this will return to the GUI and will be replace in an EDIT-TEXT box):
evaluation =
bettiamo perchè oop e calla abb spesso per floatare.
Al turn decidiamo di c/c o c/r su blank in base alla size, se cade suited c/f.
se turn abbiamo c/c e river è blank siamo in modalità vita c/c bottom-mid case: cbetptkiamo perchè oop.
Se raisa foldiamo.
Instead, if i do
evaluation= Holdem_Postflop_Decision_Tree(handles.val, handles.act, handles.text, handles.pos, handles.num, handles.bb);
and
handles.val='midv';
handles.act='rn';
handles.text='fd';
handles.pos='oop';
handles.num='hu';
handles.bb=25;
i get this error
??? Undefined function or variable "evaluation".
Error in ==> Holdem_Postflop_Decision_Tree at 6998
Moreover, if i create a Main.m like so:
value= input (' Value', 's');
action=input(' Action: ','s');
texture= input (' Texture', 's');
pos=input(' Position: ','s');
num= input (' Opponumber', 's');
bb=input(' Big blinds: ');
evaluation= Holdem_Postflop_Decision_Tree(value, action, texture, pos, num,bb);
it does work!
I really dont get it: what's the difference? I checked that all handles.field are char, and if not, i've placed at the very beginning this:
value=char(value);
actionpre=char(actionpre);
texture=char(texture);
pos=char(pos);
opponumber=char(opponumber);
I thought it was a multiple switch case problem, because if i enter the Holdem_Postflop_Decision_Tree.m from the GUI and i make separate switch-case, Matlab runs it, while it stops at the third, but now i cant think it's a multiple s-c problem, since if i put the value manually it goes through it without problem.
Any help?
P.S: i'll add the code for the string above:
case 'midv'
switch actionpre
case 'rn'
switch texture
case 'fd'
switch pos
case 'ip'
switch opponumber
case 'hu'
evaluation=' No info yet.';
case 'multiway'
evaluation=' No info yet.';
end
case 'oop'
switch opponumber
case 'hu'
if bb>15
evaluation='Cbettiamo perchè oop e calla abb spesso per floatare. Al turn decidiamo di c/c o c/r su blank in base alla size, se cade suited c/f.se turn abbiamo c/c e river è blank siamo in modalità vita c/c bottom-mid case: cbetptkiamo perchè oop. Se raisa foldiamo. Al turn se non improviamo siamo sempre in c/f a meno di info che non foldi spesso alla 2barrel, in quel caso possiamo betptkare, se calla e non improviamo river o turn è suited siamo in c/f river';
else
evaluation='cbettiamo per brokare';
end
case 'multiway'
evaluation=' No info yet.';
end
