OK, the jokes on me. You were not trying to pull one on April fools day. Your reply was Volt_humid, <[128, ...... which seemed that it's looking for a number smaller than the search number, which would almost always return an index of "0".

Reference Manual example says - lookdown2 W0,>[number, number, number.... This will not work. I tried everything I could think of to make this work, no luck.

When I reversed to less than (<) it gives me the index number of the next larger number than the search number. This means the statement says my search number is smaller or less than the number in the list so pick the next larger number and return that index number.

you are right as always Richard, on this second day of April.
