Hi everyone,
Need i little help here:
A create a variable that i called variable_a.
Then im trying to make Sum({$<id={'variable_a'}>} Costs).
It doesn't work.
Any suggestions for that?
Thanks,
Eliano
I can never quite remember the syntax without looking at my own previous uses (which I can't do now!) but try:
Sum({$<id={'$(variable_a)'}>} Costs)
or
Sum({$<id={"$(variable_a)"}>} Costs)
If neither works I'll go and look it up!

Didn't work.
Anyother suggestions?
Thanks,

I seem to remember an example being in the F1 help in Set Analysis. Have a look there.
I solve it out.
thanks
