Since you are already doing it in a loop, adding a simple counter might work for you. For example
You get your list of items.
Before the loop, you set the "RowNumber" variable to 1 or whatever row you intend to start from
You execute For Each loop
in the loop you do whatever you need to do and use the "RowNumber" variable in the "row" field.
At the end of the loop, you increment "RowNumber" by 1
So this is just an example, there might be other, better ways, but this seems to be easy to start with based on what you gave
