Fitglm error on app designer

Hi! I'm working on app designer, and trying to make a logistic binomial model of the probability of yHat as a function of Factored Crack Length, using a two-way interactions model. My code is below:

Data = [FactoredLengthColm, yHatColm];

tbl = array2table(Data);

modelspec = 'yHat ~ FactoredLenth';

mdl = fitglm(tbl,modelspec,'Distribution','binomial')

I continue to reviece the errors: .... Am I missing something in my code?

According to the error, this error comes because "modelspec " does not able to find out 'yHat ~ FactoredLenth'.

I thought you have to use "FactoredLenthColm" instead of "FactoredLenth" same for "yHat" you need to use "yHatColm".

I hope this might resolve the error.
