HELP, Paradox 5.0 time calculations

Hello,

I have posted here a before (several attempts with MSN, but I cannot read

this newsgroup with MSN because of server problems) for the same problem.

I am trying to calculate the difference in time and express the result as

an number.

For example, if a user imputs 8:00 AM for a start time, and 4:15 PM for

an ending time, Paradox should calculate total hours as "8.25"

This calculation is needed to automate a billing charges for a home child

care facility. The calculation will involve four time options.

Name -- Example Element

Arrival Time -- Arrive

School Depart -- AMDepart

School Arrive -- PMArrive

Depart Time -- Depart

A child could come in the morning or afternoon hours only, for the entire

day, or not at all.

I have tried CALC formulas in Forms, Queries, and Reports, using the

above example elements, but only get results that are less than 1 (i.e.,

0.31, -0.21, etc.).

Your help is appreciated.

Sincerely,

Daniel A. Lee
