Data screen problem

[viv.fle...@gmail.com]

Hi. The average mpg is missing on one data record. If I delete the record and reinput it doesn't recalculate. If I delete that record and the previous and re input them both, the blank mpg moves to the earlier record and appears in the later record. I've extracted the data to a spreadsheet and all looks ok. Is it a bug or a data problem?

This is causing the reports to be wrong.

Your help is appreciated.
