Hello,
I'll first give an example of my situation.

I've got a couple of value's:

A B
1 55
1 56
2 58
3 59
1 60

I'm looking for a method so i can make a list like this:
A B
1: 55,56,60

Basicly Excel has to put the value's in the following cell divided by a ,

I've come as far as making an IF function like IF(A1:A3="1";B1:B3;"Error")
Now the list of numbers (55,56,60) is in an array.

Is there any way to convert this array to the format i described?


Greetings,
Gunti
