# MS Excel : changing the counter in formula to some other than the one Excel has assumed

An excel formula looks like this

```=", " &(\$C\$1)+1
```

Here's how the data looks when I paste special --> forumulas

```    1
, 2
, 3
, 3
```

I want it to increase the LAST Number +1 in the counter . Something like

```    1
, 2
, 3
, 4
```

I can of course fix it many "work-around" ways like having 1 more column for the step up counter and then using it in the formula. Here Excel BY DEFAULT will step up the counter on Column C1 like this

``` =", " &(C1)+1
```

and increase C1 to C2 C3 ..Cn on a "paste special" ..unless you freeze it with \$C\$1 but then it's not sensible enough to consider the last +1 as the counter and use that. So the counter remains the same and the value is the same. How to tell excel to use the last + 1 as the counter

Maybe

```=", " & SUBSTITUTE(C1,", ","")+1
```

Assuming your first formula is in A1 you can use:

```=", "&(\$C\$1)+(1-ROW(\$A\$1)+ROW(A1))
```

When you copy down, the original ROW(\$A\$1) will stay the same while the second ROW(A1) will change with your copy range. Cheers,
