There are no valid cases for VAR when GRP = .. Statistics cannot be computed for this

#1
When I perform a normality test for my variables using the grouping variable named "Group", I got a warning message telling me that there are values in the grouping variable named "Group" equal ".." ! knowing that I revised all the values in it and they were all with specific values .Also the number of observations "N" in some of the variables is lower than the true number I have . Why does this happen ? and how can I fix this ?

You should start by telling us which software you're using...

That certainly makes sense to me as well ("sounds" like S+ or SAS, but who knows for sure).

If the software warns that there is a data value that equal "..". Then there is probably such a problem. A value "3.14" can easily become "3..14".
