How do you fix error when run genetic algorithm in matlab?

Hi everyone, I have used GA in matlab to solve my problem. I created a constraint function and fitness function for this problem.
When I ran the algorithm, It was error and didn't run.
Can you help me fix it?
I show you in below.
Undefined function 'fameanalysis' for input arguments of type 'double'.
Error in createAnonymousFcn>@(x)fcn(x,FcnArgs{:}) (line 11)
fcn_handle = @(x) fcn(x,FcnArgs{:});
Error in constrValidate (line 23)
[cineq,ceq] = nonlcon(Iterate.x');
Error in gacommon (line 136)
[LinearConstr, Iterate,nineqcstr,neqcstr,ncstr] = constrValidate(NonconFcn, ...
Error in ga (line 327)
[x,fval,exitFlag,output,population,scores,FitnessFcn,nvars,Aineq,bineq,Aeq,beq,lb,ub, ...
Error in threebayfifteenthstoryframeoptimization (line 58)
[xbest, fbest, exitflag] = ga(@framecost, 34, [], [], [], [], ...
Caused by:
Failure in initial user-supplied nonlinear constraint function evaluation.

We need to see the complete line of your call to ga()
It appears that in the 9th parameter, you passed in the string 'fameanalysis', and MATLAB is then trying to find a function named 'fameanalysis' to act as a constraint function.
Might I suggest that what you wanted was 'frameanalysis', that you were missing the 'r' ?
