Textbox extension - assign to a variable?

Hi,

I'm using the textbox extension here and am wondering whether there is a way to assign the value typed into a textbox to a variable?

thanks in advance for any help

Use the [get text of textfield of name] block provided by the extension to get the text currently in the text field.
