What command do I write to keep properties of my file (font, marging, section breaks,etc) Please help!

[luzavendano]

I am running this Macro in Word but it is taking away the formattinng of the file and splitting at every section break in the document. I need to keep the font, section breakes, etc once I individually split my main mail-merge document. Below is the Macro I am running. Can anyone please help me figure out the command to maintain properties after the document have been splitting?

Thank you very much!
