How I check if words from two fields match?

[William de Smet]

Hi there all,

I have a field "number 1" with a word in it (put in by user)
Next I am putting a lot of words from a remote .txt file into another field
"number 2".
How do I check if the word from fld "number1" is within the words of fld
"number2"?

For now I use:
find string the text of fld "number1" in fld "number2"

But how do I proceed?
When they match I want to use something like: answer "Well done!"

Greetings,

William
