Hey guys,

I have an CSV file where I have 4 different columns with values (column1 till column4). I'am creating in the attribute manager a new columns (column5) where I connect all the values of the first four columns with a point in between.

For example

```

column1, column2, column3, column4, column5

1, 2, 3, 4, 1.2.3.4

```

`column2` has the special that there are numbers from `1` til `99`. I want to put infront all values of `column2` which are from `1` til `9` a `0`, so that it looks like the example. But already two digits numbers should not get a `0`.

For example

```

column1, column2, column3, column4, column5

1, 02, 3, 4, 1.02.3.4

3, 65, 5, 9, 3.65.5.9

```

How can I manage this? Has anybody a clue? Or could somebody help me please?

Thanks in advance!

Have a good day!

Cheers,

Fabian
