I have the range of data like the following:

Description

Column A Column B
UAE Mobile 21
UAE 22
Bangladish-Sylhet (2) 33
Bangladish Mob 26
Bangladish Mob (1) 15
Bangladish Mob (2) 29
Bangladish Mob (3) 98

I want the totals of values in column B for the similar values in column A
to be added up. Now I need different stages of totals:

1- I need totals for all the values in column A where the first word is the
same. For example Bangladesh. But Bangladesh is separated from the
remaining text in some cases by a "space" and in some cases by "-".

2- Second I need subtotal for all the values in column A where the first two
words are the same. For example Bangladesh Mobile or Bangladesh-Sylhet. In
these cases the words are separated in the first instance by a "space" and in
the second one by the "-".

3- I want further subtotal where the first three words of the value in
column A are the same and so on and so on.........

Ny help URGENTLY!

Thanks
