Thank You Doug!

I appreciate your help. That did the trick. I am still learning and this
helped me understand some of what I learned.

Thanks, Larry

Those who fail to read the FAQ before posting commonly demonstrate
ineptness.

Evidently you have not considered the difference between rounding to a
multiple 0f 0.01 and rounding to two decimals. Currency outputs should
be rounded to the nearest penny or pound (or foreign equivalents), not
to the nearest florin (unless large, of course).

Function parseFloat is not needed in that code. FAQ 4.21.

Then, if you continue to post here what you naively think are answers,
you will continue to demonstrate your childish obstinacy, and it will
continue to be remarked upon.

Your mere ignorance and lack of understanding are not necessarily to be
ashamed of, provided that obvious steps to remedy them are promptly
taken.
