Anyone know how to make a local script variable not carry over between dialogs?

So I've been trying to make this work without melting the game. This script is supposed to subject vendor repair costs to a modifier based on barter and charisma. The question is where I hook it in. Well, there's not that many choices in the first place and I figured the best way to do it is through dialog as all vendor repairs go through dialog first.

I can't run it together with the repair window as the function needs to be executed before it even appears. Here's the script:

scn aaoRepairCostScript

begin menuMode 1009 ; start on dialog

int makeitstop
if makeitstop == 0 ; do-once loop

    float repaircostvariable ; where the result is stored
    
    set repaircostvariable to (2-(((playerref.getactorvalue barter)+(playerref.getpermanentactorvalue charisma*10))*875/100000))*aaoRepairCostMod ; calculation, with global modifier

    if repaircostvariable < 0.25
        set repaircostvariable to 0.25 ;failsafe for skills above 100
    endif

    setnumericgamesetting fItemRepairCostMult repaircostvariable ; actual gamesetting gets set

    set makeitstop to 1
endif ; end do-once loop

end

The issue here is, since the "makeitstop" variable persists between dialogs, the whole thing only runs once and never again. But if I remove it then the entire script will run all the time during any dialog. Any more efficient way to do this?

I could try to specify the different vendors but that would break compatibility with, well, everything.

If I were you I would make a second script that runs on gamemode. This one would make makeitstop 0. Just attach it to a quest. You could even cause the quest to end immediately after setting makeitstop to 0 and just restart the quest every time you enter the loop in this script you posted

If you want to do the work, sure, go ahead.
