GUi WindowScrollWheenFcn problem. Please help

Please don't delete or flag my questions.

This is important for me. Next time, I will flag other's questions as weill.

To those who have knowledge on designing GUI, please can you let me know what this error is and how can I solve it?

Warning: Setting the "WindowScrollWheelFcn" property is not permitted while this mode is active. 
> In matlab.uitools.internal.uimodemanager>localModeWarn (line 211)
  In matlab.uitools.internal.uimodemanager>@(obj,evd)(localModeWarn(obj,evd,hThis)) (line 86)
  In experiment (line 134) 

And the line I am facing problems is this

  set (hFig, 'WindowScrollWheelFcn', @mouseScroll);

Where hFig is the main figure of my GUI.

Any help please?

I am using R2017b and R2018b
