Ahh, think I've discovered why the occasional REF error kept popping up

I had used the data mentioned in your line to set it up on the sheet:
I had 40%, 10%, 30%, 10% ..
w/o realizing the percents don't add up to 100% <g
Once the above was corrected, there's no more REF error

But I'd still like to test run your sub abcd().
Grateful if you could clarify
