Help on VBA edit

Don’t have VBA experience, but have solid excel experience. I came across this great write-up for an invoice creation tool that solves a lot of what I’m looking for, except for the last step which automatically opens outlook and attaches the invoice. I am looking to have the exact same set up, but have the macro stop when the invoice saves, no email send. I tried to remove the snippet for email in vba, but it results in the invoice table not being populated and the invoice doesn’t save anywhere. Thoughts?
