Need message pop up when there is particular default error/warning message

Hi All,

Hope everything is fine.

Can anyone help me to achieve message pop up whenever it hits any specific default error or warning message?

For example: When from-date in the screen is higher than to-date, error message get raised stating the mistake. After error message hits I need a pop message to give more instructions for the user.

- Is it possible to trigger workflow in this scenario? I am new to workflow. If it is possible please guide me with ideas.

- Are could you kindly suggest any other idea for such scenarios?

Thank you,

Sangameshwari.
