修改单元格的值以在原始值之前包含“字符串”

I have a vba script that I have been working on(few hundred lines). One section of code is supposed to loop through a row of cells, and add a "string" preceding the rest of the data. I cannot figure out why this is not working, but I am suspecting I am overwriting my data somehow with the original value. Help would be greatly appreciated. Thank you.I have a vba script that I have been working on
