Why do i get this error? "Unrecognized function or variable 'prop'."

My code uses another .m file named openprop.m but somehow i cant manage to get csv files and get this error. First code is openprop.m , the other one is exportsolidworks.m. when i run exportsolids code i get this error.

clear global;  clear all; close all; clc;

I don't see, in the code you provided, anywhere where a variable called props is references. Please attach the m-files with the paperclip icon. Also give the full error message (ALL THE RED TEXT) which will give the line number and actual line of code that threw the error.

If you have any more questions, then attach your data and code to read it in with the paperclip icon after you read this:

Full error is below:

>> Export_SolidWorks_v18(prop)

Unrecognized function or variable 'prop'.

Problem is this code gives csv files as an output when i insert inputs but i think i missed something so it gaves error.

[Walter Roberson]

You are trying to invoke Export_SolidWorks_v18 passing in the single undefined parameter prop .

prop is undefined. There is no variable named prop created by openprop or OpenPropSingle.

Furthermore, Export_SolidWorks_v18 needs several parameters passed to it, Export_SolidWorks_v18(filename_SolidWorks,Np,Mp,Z,X3D,Y3D,Z3D) and you are just not passing those parameters.
