How to update seek bar value with user input

[Platonic]

When user sets the value of the seekbar, the seekbar must display the new values when user opens the gg.prompt.

The script partly works, but i receive an error the moment the second menu becomes nil.

function boolCheck()
  menuHasBeenUsed = false
  loopMenu = 0
end
boolCheck()

function loopCheck()
  charLoop = 0
  gameSpdLoop = 0
  objSpdLoop = 0
  jmpLoop = 0
  charSizeLoop = 0
end
loopCheck()

function menu()
  menuBool = false
end
menu()

function menu()
  menuBool = false
end
menu()

function START()
  if menuBool == false then
    speed = gg.prompt
    (
      {'Animation Speed | default value = 1 | [1; 10]', 'Game Speed | default value = 1  [1; 10]', 'Playerobject Speed | default value = 1  [1; 10]', 'Jump hack', 'Player size | default value = 1 [1;10]'},
      {[1]='1', [2]='1', [3]='1', [5]='1'},
      {'number', 'number', 'number', 'checkbox', 'number'}
    )
  elseif menuBool == true then
        speed = gg.prompt
    (
      {'Animation Speed | default value = 1 | [1; 10]', 'Game Speed | default value = 1  [1; 10]', 'Playerobject Speed | default value = 1  [1; 10]', 'Jump hack', 'Player size | default value = 1 [1;10]'},
      {[1]=speed[1], [2]=speed[2], [3]=speed[3], [5]=speed[5]},
      {'number', 'number', 'number', 'checkbox', 'number'}
    )
  end
  
  menuBool = true
  
  if speed == nil then
    noselect()
  else
    
    if speed[1] then
      menuHasBeenUsed = true
      charLoop = charLoop + 1
      if charLoop <= 1 then
        characterAnim()
      end
      for i = 1, #characterAnimation do
        characterAnimation[i]["value"] = speed[1]
      end
      gg.setValues(characterAnimation)
    end
    
    if speed[2] then
      menuHasBeenUsed = true
      gameSpdLoop = gameSpdLoop + 1
      if gameSpdLoop <= 1 then
        fullGameSpeed()
      end
      for i = 1, #gameSpeedFull do
        gameSpeedFull[i]["value"] = speed[2]
      end
      gg.setValues(gameSpeedFull)
    end
    
    if speed[3] then
      menuHasBeenUsed = true
      objSpdLoop = objSpdLoop + 1
      if objSpdLoop <= 1 then
        charsObjectSpeed()
      end
      for i = 1, #characterObjectSpeed do
        characterObjectSpeed[i]["value"] = speed[3]
      end
      gg.setValues(characterObjectSpeed)
    end
    
    if speed[4] then
      menuHasBeenUsed = true
      for i = 1, #jumpCount do
        jumpCount[i]["value"] = "0"
        jumpCount[i]["freeze"] = true
        gg.addListItems(jumpCount)
      end
    end
    
    if speed[5] then
      menuHasBeenUsed = true
      charSizeLoop = charSizeLoop + 1
      if charSizeLoop <= 1 then
        charsObjectSize()
      end
      for i = 1, #characterObjectSize do
        characterObjectSize[i]["value"] = speed[5]
      end
      gg.setValues(characterObjectSize)
    end
    print(speed)
  end
end

function noselect()
  gg.toast('You not select anything')
end

START()
while (true) do
  if gg.isVisible() then
    gg.setVisible(false)
    START()
  else
    if menuHasBeenUsed == true then
      jumpPointer = gg.getValues(jumpPointer)
      valueCheck()
    end
  end
  gg.sleep(200) 
end

Using some temporary fix.

if menuBool == false then
    speed = gg.prompt
    (
      {'Animation Speed | default value = 1 | [1; 10]', 'Game Speed | default value = 1  [1; 10]', 'Playerobject Speed | default value = 1  [1; 10]', 'Jump hack', 'Player size | default value = 1 [1;10]'},
      {[1]='1', [2]='1', [3]='1', [5]='1'},
      {'number', 'number', 'number', 'checkbox', 'number'}
    )
  end
  
  if menuBool == true then
    speed = gg.prompt
    (
      {'Animation Speed | default value = 1 | [1; 10]', 'Game Speed | default value = 1  [1; 10]', 'Playerobject Speed | default value = 1  [1; 10]', 'Jump hack', 'Player size | default value = 1 [1;10]'},
      {[1]=characterAnimation[1]["value"], [2]=gameSpeedFull[1]["value"], [3]=characterObjectSpeed[1]["value"], [5]=characterObjectSize[1]["value"]},
      {'number', 'number', 'number', 'checkbox', 'number'}
    )
  end

It works fine using a the tables but im not sure if its good idea for use it. I do like to know how to fix the error of the original question.

Check if the second menu is nil and set it to the default value:

if secondmenu == nil then
speedvalue = speed[1]
else
speedvalue = defaultspeedvalue
end
