hi,
I have a qvd file with a variable "Type" which has numerical values from 5000 to 7000.
These values can be categorized to products: A, B , C - but a value can be categorized to more than on product. For instance, values 5201 is also in product A and also in B.
my App has a selection for the type of products you're interested in viewing. I want to show the viewer the number of observations which are relevant to the selected product. I want to do the following steps (unless you can think of a more efficient way!) but need help with syntax:
a. create a list variable for each product and in it put all the relevant "type" numbers. for example:
set vProductA = 5501,5201;
b. create a list variable for each product which receives the value of the list variable if that product is chosen, and an empty list set otherwise. for example:
if((wildmatch(GetFieldSelections(product,';','*A*')))> 0, vProductAchoose=$( vProductA ),vProductAchoose={})
c. create a variable which is a join of step b variables:
set vProductChosen =sum({<vProductAchoose>+<vProductBchoose>+<vProductCchoose>})
d. count all observations in this new list:
=count({<Type={"vProductChosen"}>} observation)
what is the correct syntax for steps b-d?
thankyou!
