Searching a textbox for a word

Hey, basically I'm trying to get a textbox to search itself for a word, and if it's there, the event proceeds. I looked on other forums and people suggested find(text.text,"yourword"), but using this on a compare text condition for a textbox object (instead of just Text) it comes up with the "yourword" being a parameter that requires a string, not a number. Surely this is a string? Perhaps I'm missing or something, or maybe this does not work on textbox objects. Any ideas?

Ah man that looks useful, thank you, but I've spent the last hour trying to even figure it out, let alone apply it somehow to my own project. I guess I'll just have to leave it and find another way around it

If I understand correctly..you only need Yes(it's there) or No(there's no such word.. )
