My php error log is full with this error message:

PHP Warning: number_format() expects parameter 1 to be double, string given in /koolreport/core/src/core/Utility.php on line 147

This is occuring where I have numbers formatted according to specs in examples and docs in DataGrid layouts.

Thanks for looking at this...

This is from my view page, pulled out the php portions.

As soon as I read your note, then looked at the error message again, I opened up the table structure and sure enough, the neg_price is a string. I assumed it was a number based on my field description. I changed to a string, tested the form again, and the error messages are gone. Thank you for pointing me in the right direction.
