How to update a variable in corona SDK?

I have a function, which changes the variable from what it was to something new. I am using load-save .json tables to get and load data. How do I update the startmoneyTxt to display the new variable?

My function:

local function unlockBall(event)
  ballfirst = loadsave.loadTable("firstBall.json", system.DocumentsDirectory)
  currentMoney1 = loadsave.loadTable("cashTable.json", system.DocumentsDirectory)
  difference = currentMoney1 - ballfirstUnlock

   if(ballfirst == 0 and difference >= 0)then
    ballfirstID = 1

      loadsave.saveTable(ballfirstID, "firstBall.json", system.DocumentsDirectory)
      loadsave.saveTable(difference, "cashTable.json", system.DocumentsDirectory)

   end
end

My code which should be updated:

currentMoney = loadsave.loadTable("cashTable.json", system.DocumentsDirectory)
startmoneyTxt= display.newText("$ "..currentMoney.." " , 0,0, "Helvetica", 20)
sceneGroup:insert(startmoneyTxt)

Whenever you want change text use

startmoneyTxt.text = "Your text here"

Note: As names saveTable and loadTable imply functions are indent to save/load tables. So you can use one file to save/load multiple values.

I use loadsave module to save/load setings in my game The Great Pong.
