Error message: "The 'cf' start tag on line 7 does not match the end tag of 'P'. Line 12, position 55".
I do not know: what the lines 7 and 12 refer to;
what the 'cf' and tag is
what 'P' is
How to fix the problem?
Clear the target cell of the segment and Copy the whole source segment to target segment (Ctrl+Insert) then re-translate the segment without touching any tags.
Hope this helps.
