Duplicated words in table

[miro_kopecky]

Hi, I have table, which contains 3 columns. (as you can see in the Picture)
First column means from which file Word in the third column comes from.
Second column means how many times is Word located in that file from where it comes from.
I need to create 4th column where will be counted how many times is one Word located in whole 3rd column.
For Word 'Zuzana' it should be 2 because there are 2 words zuzana in 3rd column.
For Word 'Zruč-Senec' it should be 1 because there is only 1 Word zruč-senes in 3rd column.
For Word 'Znojmo' it should be again 2 and so on...

I dont have many experience with script writing in Qlik so I am asking for help.
Thank in advance.

Something like sum(TOTAL <Matched> WordCountRight). If that doesn't work then we'll need more information about the names of the fields used and the expression you use to calculate the values in the second column.
