matlab embedded function (MATLAB R2008a)

I have a simulink model with embedded MATLAB function which code is

function [t,p,h,hv,hl,v,v_v,vl,s,sv,sl,u,uv,ul,x] = fcn(t1,p1,h1,v1,s1,u1,x1)
%#eml 
eml.extrinsic('XSteam');
t = zeros(1,1,'uint8');
p= zeros(1,1,'unit8');
h=zeros(1,1,'unit8');
hv=zeros(1,1,'unit8');
hl=zeros(1,1,'unit8');
v=zeros(1,1,'unit8');
v_v=zeros(1,1,'unit8');
vl=zeros(1,1,'unit8');
s=zeros(1,1,'unit8');
sv=zeros(1,1,'unit8');
sl=zeros(1,1,'unit8');
u=zeros(1,1,'unit8');
uv=zeros(1,1,'unit8');
ul=zeros(1,1,'unit8');
x=zeros(1,1,'unit8');
if ((t1==0)&& (h1==0)&& (v1==0)&& (s1==0)&& (u1==0)&&(x1==0));

    t=XSteam('Tsat_p',p1);
    p=0;
    hv=XSteam('hV_p',p1);
    hl=XSteam('hL_p',p1);
    v_v=XSteam('vV_p',p1);
    vl=XSteam('vL_p',p1);
    sv=XSteam('sV_p',p1);
    sl=XSteam('sL_p',p1);
    uv=XSteam('uV_p',p1);
    ul=XSteam('uL_p',p1);
    h=0;
    u=0;
    s=0;v=0;x=0;
elseif ((p1==0)&&(h1==0)&&(v1==0)&&(s1==0)&&(u1==0)&&(x1==0));
     p=XSteam('psat_T',t1);
    hv=XSteam('hV_T',t1);
    hl=XSteam('hL_T',t1);
    v_v=XSteam('vV_T',t1);

    s=XSteam('s_pT',p1,t1);
    v=XSteam('v_pT',p1,t1);
    u=XSteam('u_pT',p1,t1);
    p=0;ul=0;uv=0;sl=0;sv=0;v_v=0;vl=0;hv=0;hl=0;x=0;
    t=0;
elseif ((t1==0)&&(h1==0)&&(v1==0)&&(u1==0)&&(x1==0));
    x=XSteam('x_ps',p1,s1);
     u=XSteam('u_ps',p1,s1);
     v=XSteam('v_ps',p1,s1);
     t=XSteam('T_ps',p1,s1);
     p=0;
     s=0;ul=0;uv=0;sl=0;sv=0;v_v=0;vl=0;hv=0;hl=0;

      x=XSteam('x_ph',p1,h1);
      p=0;
      h=0;ul=0;uv=0;sl=0;sv=0;v_v=0;vl=0;hv=0;hl=0;

    h=0;s=0;ul=0;uv=0;sl=0;sv=0;v_v=0;vl=0;hv=0;hl=0;x=0;

    u=0;s=0;p=0;x=0;ul=0;uv=0;sl=0;sv=0;v_v=0;vl=0;hv=0;hl=0;

end

but when I run the model some errors display ""Sampled update was specified and no sample time was entered in chart Embedded MATLAB Function (#18)""

and ""Error reported by S-function 'sf_sfun' in 'steam/Embedded MATLAB Function/ SFunction ': Stateflow Suppress Error.""

Please do not open duplicate questions; it stresses and confuses the editors.
