First of all: Why are you still not using Do it?
As we can see, value is a single list and not a list of lists...
the question is, why are you using a for loop?
just remove it and use an if then else statement instead
And as the text in the textbox is 1000 and your text you are trying to get is 100, the if statement is false, so 1000 was not found, which results in your notifier "NO EXISTE" which is exactly what you were asking for
