Maximum = 100 Minimum = 0 value in a field? what is the code please

Although you could create a script for this, you can also use the built-in method that you'll see on the validate tab of the field properties dialog. It allows you to specify the minimum and maximum values for fields with a numeric format.

Have you looked at the "Validate" tab on the "Properties" pop-up window for the field?

The field needs to have the Number Format, and then the option for the value range will be available.

There is a built in function, AFRange_Validate(bGreaterThan, nGreaterThan, bLessThan, nLessThan), that could also be used.

Or you can use a custom validation script like:

nMin = 0; // greater than or equal to min;
nMax = 1000; // less then or equal to max;
if(event.value < nMin | event.value > nMax) {
app.alert('Invalid value: \n value must be \n\tgreater than or equal to ' + nMin + '\n\tor less than or equal to ' + nMax, 1, 0, 'Validation Error');
event.rc = false;
}

Hi, thank you very much for your help. I didn't have the number format selected so couldn't get the option for the value range. But I ended out using your custom validation script as it appears more professional on input of wrong info. Thanks again.
