Help to a couple of codes in VBA PowerPoint 2019

Hi PowerPont Experts.

I'm a little new in using VBA in PowerPoint.
I've used VBA in Excel, but it doesn't seems to be similar with the VBA in PowerPoint.

Instead of writing about my problems here, I've written it all in the attached PPTM.

1. Please download the attached PPTM.zip
2. And if possible, type the codes in the Active TextBoxes and resend it to me.

I'm sorry I needed to attach it as a ZIP, but it was the only way I could attach the PPTM.

Thank you in advance
