Cannot run the macro

Hi I need some help, when I send the project to my manager they received error (please see attached screenshot). but on my desktop it works well.

Thank you

If the picture click by the user the Sheet 2 or the userform will show.

the questions are:
1) is the vba code imbedded in the workbook
2) what security settings has your manager got, does it forbid macros go to excel options_the trust centre_macro settings on your managers computer

the questions are:
1) is the vba code imbedded in the workbook - Yes
2) what security settings has your manager got, does it forbid macros go to excel options_the trust centre_macro settings on your managers computer - I'm not sure with this, but the workbook itself I already set to Enable Macro and Trust access to the VBA project object model. or should I still need to setup the same security to my manager compute?

I got it, my manager forgot to click enable content on the workbook. Thanks!
