How do I find Line numbers on FTM

[vallee]

I imported a file into it last last night and got the errors pages 2 of them which is unusual for me
Thing is I dont remember how to find line numbers on there
Most say
Tag MARR subordinated to wrong item line ignored
Some say Tag MARR invalid date
can anyone explain this please and how do I number and find the numbers of the people in my tree thanks

I don't know how you find the line numbers exactly, Val, but where did you get the GEDCOM from that you uploaded?
