If you want to look for an empty cell -- no formula that evaluates to "".
if isempty(worksheets("Somesheetnamehere").range("A1").value) then
'it's empty
else
'it's got something in it.
end if
checking for "" with something like this may not be enough:
if worksheets("Somesheetnamehere").range("A1").value = "" then
'cell looks empty, but it may have a formula that evaluates to ""
'it may even be empty
else
'cell has something in it for sure
end if
