Hi @Pippobaudo89 , @HansS 's solution is clearly the solution for this question, but just thought I’d add that if you had any kind of mathematical progression, you can always use Math Formula by calculating using ROWINDEX (which starts at 0)

e.g.
1,2,3,4,… ($$ROWINDEX$$ +1)

10,20,30,40… ($$ROWINDEX$$ +1) * 10

1,4,9,16,25,36,49… ($$ROWINDEX$$ +1) ^2

(and sometimes I use Math Formula instead of Counter Generation if I need several counters just because it allows me to name the counter )
