Hi all.
Am very new to crystal and what I want is to display percantages from two crosstabs on a text field.
This is the format;

Department1 100 50 60 0 210
Department2 10 20 30 20 80
Department3 20 20 100 0 140

Crosstab2
item1 item2 Total
Department1 100 50 100 Textfield1
Department2 10 20 30 Textfield2
Department3 20 20 40 Textfield3

Crosstab2 is reporting SOME of the items in crosstab1

Textfield1 is to display 100/210 %
Textfield2 30/80 % and
textfield3 40/140 %

Please assist.
