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:

a=newfis('FuzzyControlu1');

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,
