PowerPoint macro to toggle multi words on slide to change font size & color in order from left to right. MouseOver toggles the change - vba

Question

I’m creating reading materials using PPT slide. Each slide contains a series of rectangle shapes containing a word - text color is black.Rectangles are named 1, 2, 3, 4, 5, 6 … Rectangle shapes run across the page. Macro MouseOver is assigned to all rectangle shape on slide. At the start of presentation: 1. several global variables are set. 2.Rectangle named 1 will increase in font size, text color to red. Mouseover on Rectangle 1, font size & font color returns to original size & color for Rectangle 1 and Rectangle 2, increase font size & change text color to red. When mouseover Rectangle 2, change font size & font color returns to original size for Rectangle 2 and for Rectangle 3, increase font size & change text color to red. In general, mouseover returns text to normal size & color and change color & size of next word in order. The order is 1, 2, 3 ... based on the name of Rectangles.
Thank you.
Trying to code with code found on website:
Update: I got StartSetUp to work. Having trouble declaring global variables - NumCnt & Last. I just discover Visual Studio Editor to type in code. Editor is a big help. Will work on MouseOver tomorrow.
Update 9/10/2022: Got it working. Need more testing. Macro is not pretty. I'm new to PPT. I learned a lot reading all the questions and answers on this site. Thank you everyone!
Update 9/11/2022: I believe it works. Closing.
