You copy your match's Overall results, paste them in, and get "Couldn't find any result rows." The paste usually isn't the problem — PractiScore just has two different pages for the same results, and you may have grabbed the other one.
PractiScore keeps two Overall-results layouts
The modern view lists each competitor as one fused line — 1-Dustin Bobst — with Name as the lead column. Every match page also has an older layout one click away, behind a link near the bottom labeled Old style results. It's the same field and the same standings, just split into separate Place and Name columns, with Place leading instead of Name.
How to tell which one you copied
If each row in your paste starts with a number fused straight into a name (1-Dustin Bobst), you have the modern view. If each row starts with a bare number, then a name written Last, First in its own column, headed by columns like No., Match Pts, and Match %, you have the old-style view.
Both work in MatchChaser
Paste either one — the importer recognizes both. The one real difference: the old-style page doesn't carry per-hit A/C/D/M/NS counts, only placement and percentage. If you want the full hit breakdown in the row picker, grab the modern page; if you just need the match on record, the old-style page is fine as is.
Still coming back empty?
Make sure you copied the whole Overall table — header row included — and that it's the Overall results, not the per-stage breakdown, which is a different page entirely.
