How to solve "attempted to call field "Value" (a number value)" error?

Asked by

This script is supposed to display the score on a practical test out of 8, it does the theory score fine but throws an error when doing the Practical Result. I've made sure that PracticalResult does have a value inside game.Players.Local player and yet I get the error: attempted to call field "Value" (a number value)

Help is much appreciated MD


function onClick()
    PracScore = game.Players.LocalPlayer.PracticalScore
    script.Parent.Parent.Visible = false
    script.Parent.Parent.Parent.OverallResult.Visible = true
    script.Parent.Parent.Parent.OverallResult.TheoryResult.Text = "You scored: "..script.Parent.Parent.Parent.Score.Value.." out of 10"
    script.Parent.Parent.Parent.OverallResult.PracticalResult.Text = "You scored: "..PracScore.Value " out of 8" -- error occurs here

end

script.Parent.MouseButton1Click:connect(onClick)

When you insert a value into a string, you need the periods on both sides.

Line 6:

script.Parent.Parent.Parent.OverallResult.PracticalResult.Text = "You scored: "..PracScore.Value.." out of 8"

The cause of this syntax error being "calling" is because the parenthesis are optional around function arguments if the args are literal tables or strings. For example, `print "hi"` works without parenthesis. In this case, you have `PracScrore.Value "out of 8"` which syntactically is the same as the previous snippet--hence, calling a number (.Value).
