...with the numbers of 2 others columns simply appended? Example : I have a column with provinces codes (1 to 19) I have a second column with districts codes (1 to ##, depending on the province) I want to create a third column with a code that would be unique for each district: Province  District   District_Unique 1             1            11 1             2            12 13           2            132 I can create a loop, but it becomes complicated with numerous data Thanks for your help [[alternative HTML version deleted]]
