Just for grins, try this
=COUNTIF(E:E,"*1*")
that seems to work with spaces and the non-breaking space character (Char(160)) which can be present if you copied your data from the web.
It won't count a number like 1, 123 or 2114 if they are stored as numbers.
However you statement that there is a problem with the formula would not be raised because of the data. It generally implies that you have improperly formatted the range argument or are using something like a semi-colon (;) for list separator when you actually
need a comma (,) (the first argument can only be a reference to a single contiguous range)
