A BeforeSave that I can't do

Hi!!
I need a macro or code to prevent saving if the correct data is not entered.
I have this workbook and if the Status column says Inactive it will mark the Reason column in yellow and promt to Select option, but until they not select a valid option the workbook can't be saved, how can this be done?
I need that a message popup and says "Please complete the information before saving"

I attached my file so it can be better understand

TestSave.xlsx

Appreciate your help
