extra column in crosstab

[sirpelon]

Hi everyone

i need your help, i have a report that uses a crosstab for show the information in this way

modelo1 modelo2 .... modeloN total
defecto1 0 2 0 2
defecto2 5 3 0 5

defectoN 10 0 3 13

I need to show an extra column showing a percentage next to the total column, something like this

modelo1 modelo2 .... modeloN total %
defecto1 0 2 0 2 0.08
defecto2 5 3 0 5 0.15

defectoN 10 0 3 13 1.20

Is there someway to add the percentage colummn to the crosstab? or what can i do to acomplish this.

Thanks in advance.
