 Seeing the problem is knowing the solution, or something
like that. When you have entered the new price into "cd fld
price" , instead of moving it to line 1 of cd fld
"tracking", move line 11 of cd fld "tracking" to line 12 of
cd fld "tracking", and line 10 to 11 etc. This will leave a
hole in line 1 of cd fld "tracking", into which you can move
line 1 of cd fld "price".
Luck.
