Escape (double-up) your backslashes in double quotes, or place your
filepath in single quotes.

Change this:

wb = xl.Workbooks.Open("C:\Documents and
Settings\mpf18.MPFD18\Desktop\Achievement-with Target(JNJ-Wise)")

To this:

wb = xl.Workbooks.Open("C:\\Documents and
Settings\\mpf18.MPFD18\\Desktop\\Achievement-with Target(JNJ-Wise)")

Or this:

wb = xl.Workbooks.Open('C:\Documents and
Settings\mpf18.MPFD18\Desktop\Achievement-with Target(JNJ-Wise)')
