Automation Error when executing SQL Server Script in Excel VBA - sql-server

Question

I am opening an SQL Server Connection in EXCEL VBA and on the objMyCmd.Execute line when it is using the SQL script I am getting this error message:
"Run-time error '-2147217900 (80040e14)') Automation error"
I have reviewed other SO posts that seem to reference an issue with the connection string itself, but I don't believe that is the issue as I am able to pull the first few variables listed when eliminating the rest of the SQL script.
I have attempted to review the SQL code to see if I am using an incorrect format, or if the language is not written properly and I am not able to determine the issue. I am hoping with some Q & A we may notice something I have missed in how this is written? Please let me know if there is additional information I can provide, below is the code up to the point of error.
