我是开发新手,在尝试编译下面的代码时收到错误"Expression Expected".我究竟做错了什么？

Public Class Form1

    Private Sub btnCompute_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCompute.Click

        Dim Occupation As String = CStr(txtOccupation.Text)
        Dim Bill As Double = CDbl(txtBill.Text)
        Dim Tip As Double = CDbl(txtTip.Text)

        lstOutput.Text = Bill * (1 + if (Tip<1,Tip,Tip/100))

    End Sub
End Class

我需要计算赢得的游戏和游戏丢失的百分比.我一直在犯错误,这让我陷入困境.我已经多次更改了我的代码,以至于当我开始时我并不记得它是什么样的.

Private Sub btnPercentage_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPercentage.Click
    Dim team As String
    Dim won, lost, percentage As Integer

    team = CStr(txtTeam.Text)
    won = CInt(txtGamesWon.Text)
    lost = CInt(txtGamesLost.Text)
    percentage = CInt(txtPercent.Text)

    percentage = (won + lost) / 2

    txtPercent.Text = team & " won" & percentage & " of its games."
