If you try to use it to get the text size of the active field, and the active field's text has not been resized from the field's default size, returns null string (""), not the text size.

I find this works better, especially if there are numerals in the text. Obviously a nul value is returned if the text side has not been modified from the field default size. You can write in a formula to replace the nul value with your default value.

GetAsNumber ( Middle ( GetAsCSS( text ) ; Position ( GetAsCSS( text ) ; "font-size: " ; 1 ; 1 ) +11 ; 4 ) )
