Cannot convert text to a number

What happened

You tried to enter text in a field with a number data type, or preceded a valid number with a text character.

For example, you see this message if you try to enter any character but a number in a field in the Text Properties box where a number is required, such as Left margin.

What you can do

If this problem occurs in IBM® Notes®, enter a valid number.

If you are a designer and entering a formula in a field, use the @TextToNumber function to convert the text to a number. When you use the @TextToNumber function and it fails, the result is @Error rather than this message.
