Do read it right that you have 2 extra line between your trap line (presumably the original line 1?) and your collection of data fields?
Nothing else changes?
2 things. You may need to check that the last lines of you records are not dropping off the end of (assumedly) extended records. If they are you need to make the sample lines selection a little longer. Easiest way woule be to select a newe sample and use the approriate button to replace the old one.
As for the fields. best way I know would be to use the "Field List" feature and simply edit the line numbers for each of the fields. You need to do it in the right order since Monarch will check to ensure there is no possible overlap of field in the template. Therefore you will probably need to start with the last row, adding 2 to the line number, and work upwards.
