What I need help with is the following:
I would like to have it so, that when I fill in information on one row in
the main document (sheet 1), that the whole row (in sheet 1) automatically
will be copy/pasted in the correct underlaying sheet per category (I have
different sheets for different categories).

In the main document (sheet 1) the information is divided into different
product types in each row - however there are about 10 different product
types / categories. When "product 1" is put into the main sheet it would be
nice if this automatically is shown under the sheet "summary for product 1".

Doing so enables me to have a correct sub-total per category which can
eventually be linked to the "total-sheet".

Any suggestions on how to do this correctly? Hope you understand my question
:-)
