When you're done with all scripts, this is how to use flags so scripts don't repeat:
Say you have placed a script (called "script" in this example) which contains the commands:
say(1)
Text
reply(1)
Text
Delete the script box (not the actual script but only the box which you walk through) and replace it with a script with the same name, but with something like "_load" after it. (so you walk through a box with the script "script_load" in this case). script_load should contain this:
ifflag(1,stop)
flag(1,on)
iftrinkets(0,script)
Do this for every script you don't want to repeat (replacing the red things in the _load script with flag numbers for each script and the name of the actual script).
