Hello there,

I making a simple app that reads numerical data inputed by the user and outputs arrays of data as result of some formula. In one of the callback functions, I have a while loop which, after the conditions is fulfilled, gives an array as a result. The function works correctly in the editor but in the app designer, it fails to recognise all the variables that are in the while loop.

Can anyone suggest what would be the possible reason behind this?

Thanks

You probably have a scoping issue. Shared values are typically stored variable names such as app.myVariable

To give any more specific help you would need to provide the code you are using and the detailed error messages that you are receiving

WheelTravelFAW.m

hey Jon, thanks for getting back. I have attached the code now. Also, below is the code in the callback in the app designer looks and error message:

% All inputs from the user

K_FAW = app.CoilStiffness1NmmEditField.Value;

W_FAW = app.UnladenloadperwheelkgEditField.Value;

MR_FAW = app.Motionratio1EditField.Value;

BST_FAW = app.UnladentoBStouchtravel1mmEditField.Value; %unladen to bump stop touch travel

WCC_FAW = app.InitialwheelcentrecoordinateEditField.Value; % inital wheel centre position

[WT_FAW,Total_BSLoad_FAW,Total_Load_FAW] = WheelTravelFAW(K_FAW,W_FAW,MR_FAW,BST_FAW);

Error message:

Please ignore that I have already corrected that but it still fails to recognise y_FAW basically the outcome of the while loop.

If you need more help please post the full error message you are now getting and even better attach enough code to reproduce the problem
