.M file not responding correctly

hello,

i'm a university student and i'm work with some friends on a assignment. we need to make 2 .m files,

• the first one is a simulation of the visitors of a shop using weibull commands, and this file works great
• the second .m file needs to be a simulator that will calculate the possibility of the visitors being below "x (in a number of visitors ofcourse) that didn't visit the shop between 10-18h, so for example :

I type "1000 visitors" and he will calculate the chance in % that there wil be less then "1000" visitors.

so for i got this, but i cant get the second file to work.

hopefully you can help me solve this problem.

Can you please attach the actual .m files instead of the images?

Note: We do not have the definition of "beursbezoek" function. The error is happening in that function.
