Figures and equations numbering

[antros48]

Hi all, I am writing my dissertation and i have an issue with numbering on figures and equations. I want them to include the chapter number which means that for sub-chapter 1.2.1 figure 2 will be shown as Figure 1.2.1-2 and so as the equation which was created using the Seq Eq method.
However under References when i select insert caption under numbering on the point where Chapter Starts with Style, if i select Heading 1 the result will be Figure 1-5 and when i select another level, like Heading 4 the result will be again invalid such as 1.2.1.1-1.



Is there anyway i can troubleshoot and fix this situation?

Thank you
