Error while using fuzzy logic controller in a simulink model

Hi,Help please,i use fuzzy logic controller in a simulink model and i build the entire flc from the command line using Fuzzy Logic Toolbox commands.when i try to run my Simulink model, i obtain this error:
MF 'trampf' does not exist!
??? Error using ==> evalfismex
Exiting ...
Error in ==> evalfis at 84
[output,IRR,ORR,ARR] = evalfismex(input, fis, numofpoints);
this is my code:
%FuzzyControlu1
a=newfis('FuzzyControlu1');
a=addvar(a,'input','e(T)',[-510 490]);
a=addmf(a,'input',1,'N','trampf',[-510 -510 -110 -10]);
a=addmf(a,'input',1,'Z','trampf',[-110 -10 190 290]);
a=addmf(a,'input',1,'P','trampf',[190 290 490 490]);
a=addvar(a,'input','deltae(T)',[-20 20]);
a=addmf(a,'input',2,'N','trapmf',[-20 -20 -10 -4]);

excuse me,when i run my simulink,I have another error :
Error in 'HIVPID/Atomic Subsystem/Fuzzy Logic Controller1/FIS S-function' while executing C MEX S-function 'sffis', (mdlStart), at time 0.0.

Just like the error says, there is no membership function trampf, but there is a membership function trapmf (trapezoidal membership function).
Fix this typo in your code and everything should work.
HTH,
