How can I apply validation to a field so that it accepts numbers only. My issue is a decimal point. 123 is a valid entry. 1.23 should fail validation.

Why not just use the Filter Function

Filter (YourNumberfield ; "0123456789" )

123 is a valid entry. 1.23 should fail validation.

Why? There is a difference in the numbers of 121.77

Lee Thanks for your interest

The field is used to input time in a contest scoring program. Depending upon the application, the entry is either hours and minutes or minutes and seconds. Enabling the scorekeeper to enter whole number allows for faster data entry. No punctuation is necessary to separate the hours from minutes or the minutes from seconds. The entry is converted by a formula (calculation)into all minutes or all seconds. For instance, 115 converts to 75 minutes.

I'm trying to invalidate an entry that contains any characters other than numbers. Maybe I don't understand how to use the filter function but it didn't work for me.

BTW I see that we're just across the river from each other.

Try to validate by this calculation:

IsEmpty ( Filter ( Self ; KanjiNumeral ( Self ) ) )

I tried that. While I don't understand what it does (more reading required) it did cause a validation failure. That's the good news. The bad new is that by choosing "Revert", ALL changes to the record were reverted. Not just the subject (time) field.

This is how validation works: all NOT saved data of the record will be lost.
