Hello,
I have a database with multiple columns. I use on of theses columns in a combobox to filter. My issue is that in the colunms there is sometimes more than one letter :

Instead of this I would like to have a list of 1Letter/row wich allows searching on my database and sorting the items with one and several letters.
To do this I tried to create a collection but it doesn't work :
OnStart :
ClearCollect(newletters;
Distinct(
Split(
Concat(table1; letters; ",");
",");
Value)
)
Someone have an idea ?
Thanks in advance,
