I hope some of this helps you. In a script, you could say:

IF %TIME >19 THEN
BEGIN
    IF %TIME < 25 THEN
    BEGIN
        $PAGETEXT := $PAGETEXT + "This text is added to the page, if time is between 20 and 24."
    END
END

Note, when mentioning a variable in a script, you simply put one % in front of it, to say it is a variable. Also, if you want to see if 'A' equals 'B', you use the = sign. But if you want to make 'A' equal 'B' you must type := instead, not just =.

If you type the page text as you want it, as you normally would in the page editor's text box, you can then use a script saying $PAGETEXT := $PAGETEXT + "more text" to add the words "more text" onto the END of the page. If you want the "more text" to be at the start, or in the middle of the page, then you need to script all of the words of the page's text.

So, you would need to have a script that read something like:

$PAGETEXT := "type all your beginning text here. Use <br> to start new paragraphs, and html code <b> </b> etc, for formatting your text."

IF %TIME >19 THEN
BEGIN
    IF %TIME < 25 THEN
    BEGIN
        $PAGETEXT := $PAGETEXT + "This text is added to the page, if time is between 20 and 24."
    END
END

IF %TIME >4 THEN
BEGIN
    IF %TIME < 21 THEN
    BEGIN
        $PAGETEXT := $PAGETEXT + "This text is shown instead, if time is between 5 and 20."
    END
END

$PAGETEXT := $PAGETEXT + "Type all the text that comes after your 'variable text' here."

IF %COUNTER := 3 THEN
BEGIN
     IF %TIME := 24 THEN
     BEGIN
          %COUNTER := 0
          %TIME := 0
     END
END

Simply check if the first variable is what you want, then insert a check to see if the second variable is what you want, then write what you want it to do. You could keep inserting checks on more and more variables if you wanted. For example, if counter = 3, and if time = 12, and if weather = 3, then show text "it is raining in the middle of the day."

If this is relating to the "changing variables when clicking on a link" question you posted earlier, you would add the above script to your Global Links script.

Also, do you have to include all the tabs, because I've noticed the further down you go, it goes out and in. Do I have to do that? The way you did it was:

IF %COUNTER := 3 THEN
BEGIN
END

Would it be okay if I just did:

IF %COUNTER:= 3 THEN
BEGIN
IF %TIME := 24 THEN
BEGIN
%COUNTER := 0
%TIME := 0
END
END

Sorry, yeah you don't have to put the tabs in. It works fine without the spaces. I do it by habit, since it makes it easy to see what's going on in the script. (Especially if there's five or more variables being checked, with more than one of them doing stuff.)

Actually, in the editor, TAB doesn't work - in internet explorer, it moves the cursor to the next active window or object. So, I've got to press the space bar three or four times to indent things. Groups of spaces don't make any difference to the script. You can also press ENTER to put gaps between lines, as much as you want.

There is nothing wrong with the script. I copied and pasted your post into a blank game, with just your script on a page, and a link that added +1 time every time I click on it, and another that changed the weather variable when I clicked on it, and they both worked perfectly.

My only thought is, have you gone to the Story Properties page, and down to [Change Editor Features], and made sure that Scripting and Variables are both set to Advanced.

In scripts, you always refer to variables directly, and use the format %VARIABLE.

So, in the above script, you could have:

$PAGETEXT := $PAGETEXT + "<br><br>Vitality: " + %HP + "/" + %MAXHP
$PAGETEXT := $PAGETEXT + "<br>Mentality: " + %MP + "/" + %MAXMP

I usually put things that are on different lines as their own script line, so I get an idea of the page's layout. However, you can also lump it together on one line, using another + sign, like this:

$PAGETEXT := $PAGETEXT + "<br><br>Vitality: " + %HP + "/" + %MAXHP + "<br>Mentality: " + %MP + "/" + %MAXMP

By typing the + sign, you're telling it to add whatever follows the + sign onto whatever you've typed so far. Whenever you tell it to + a variable onto $PAGETEXT, it will display the current value of that variable at that spot on the page.
