Modifying Contents Of A Cell Using Other Cells

I do not have excel or an xls for a sample, I will try and restate the question.

In Cell A1 It will be used for copying the contents of and pasting the completed information into web browsers.
In Cell A1 You will find This information contained and formatted in one cell alone.

Figure-1
A1=

Information About Company
Brief Story About Company
Product Name: (X)
UPC Number: (Y)
Serial Number: (Z)
Terms Of Sale
Etc

End Figure-1

I want to essential Modify (X)(Y)(Z) using different cells one for each variable. "All completed information will be found inside of A1"

Having Cell B1-B9 Being used as labels "Product Name" "UPC Number" "etc" and using cell C1-C9 to input variables for = (X)(Y)(Z)(ETC)

In reality from cell A1 will change dynamically, but some information will need to stay constant.

Every thing In B column will just be labels.
Every thing In C will be for variables.
