Ive got the above code so it adds "Hello" to the text in the textbox, but what is the opposite to this, that will allow me to take out the word "Hello"?

Ive tried Textbox1.text = Textbox1.text - "Hello" but it doesnt work

I do not want Textbox1.text = " " because i do not want to clear the rest of the text in the box, just the word hello. thanks alot.
