Tony - 2nd arg of For Loop means to continue looping *while* the condition
is true, not *until* it is true. You have initialized Stop to zero but then
told the Loop to keep looping as long as Stop >0. You should change the ">"
to "==" ( 2 equal signs ), *but*...
Now that I have looked closer at your code, it is also wrong that you are
using array-based IIF inside the loop - to walk the arrays, you should be
using IF ( non-array ) and [] subscripts to check each element one at a
time. It is usually easier to just use array-based AFL - does the code I
gave you yesterday work?
