JB:

function lineItemOffset targetText,searchString
   put the number of items of line 1 of searchString into itemsPerLine
   replace return with comma in searchString
   put itemOffset(targetText,searchString) into rawItemNumber
   get rawItemNumber mod itemsPerLine
   if it is 0 then return (rawItemNumber div itemsPerLine)&comma&itemsPerLine
   else return ((rawItemNumber div itemsPerLine)+1)&comma&it
end lineItemOffset
