stuck with macros
 

put simply, I am looking for a macro that upon being run will compare data on
one sheet to data on another, if the info is different it will insert a row
and put the new data into the sheet, if possible too it will pull this data
from several different sources of variable length and put it into the one
sheet with no gaps and keeping user entered data aligned on both sides of the
updated info. thanks with any help,, I am stumped..
