Problem with charachter " in a text field

Hi to everybody,
i have a problem with the text field (with single line).
I need to write a string like this
book title “book one”
but scriptcase doesn’t insert the string.
I tried to call with { } the string but i see only book title but not the part between " ".
How can i solve it?

Thanks and regards!

use on beforeinsert/update the statement addslashes. I.e. {myfield}=addslashes({myfields})

Thanks for your answer.
I solved that problem but i have another ones.
In a select field i need to select a string with " character but, when i change the selection, it says invalid data. How can i use the addslashes() function in this case?

Thanks and regard.
