I have the same blocks in the same order in different screens with some changes and I am using the IF Then and Else, for some reason screen 2, 3, and 5 work but 1 and 4 do not. Also my alert notice appears sometimes but not always and there are times when it says the message of the else when I did the action of the if, I really need help, the weird thing is that the first time worked, and now it does not.
You only get 10 screens.
Don't waste them.
Reuse them.
Switch screens correctly

In addition to what @ABG and @Taifun have already said, please be careful in using the block Compare Texts with the equality. Sometimes there are hidden characters like Carriage Return, or LineFeed, or Blanks that you can't see, but their presence foolishes the equality.
I don't know how TextBox1 is made, but most probably it would be better to use a search in the TextBox1, like:
Another hint is about the use of many screens: typically it is better to use "virtual screens" to ease the variables passage between them and to avoid many other troubles (search the forum with the tag "virtual screens").
Best wishes for your project.
