Overflow error

[Chris11246]

Whenever I try to run my program it keeps giving me an overflow error and I dont know why. The problem is shown when i call this sub:

blueP.shootBall(blueS.x, blueS.y, blueP.ang, blueP.captured, ball.x, ball.y, ball.velx, ball.vely)

this is the sub

Public Sub shootBall(ByVal x, ByVal y, ByVal ang, ByRef caputred, ByRef xb, ByRef yb, ByRef velx, ByRef vely) 'x and y are blueS.x and y
        xb = System.Math.Round(x + ((18 - System.Math.Sqrt((x + 12 - (xb + 6)) ^ 2 + (y + 12 - (yb + 6)) ^ 2)) * System.Math.Cos(ang)), 5) 'moves ball out of capture range
        yb = System.Math.Round(y + ((18 - System.Math.Sqrt((x + 12 - (xb + 6)) ^ 2 - (y + 12 - (yb + 6)) ^ 2)) * System.Math.Sin(ang)), 5)
        caputred = False
        velx = 2 * System.Math.Cos(ang)
        vely = 2 * System.Math.Sin(ang)
        'Form1.Timer1.Stop()
        'MsgBox(velx & " " & vely & " " & System.Math.Sqrt((x + 12 - (xb + 6)) ^ 2 + (y + 12 - (yb + 6)) ^ 2))
        'Form1.Timer1.Start()
        xb += velx
        yb += vely
    End Sub

all the numeric variables should be decimals

it runs when I comment out these parts

xb = x '+ ((18 - System.Math.Sqrt((x + 12 - (xb + 6)) ^ 2 + (y + 12 - (yb + 6)) ^ 2)) * System.Math.Cos(ang)) 'moves ball out of capture range
        yb = y '+ ((18 - System.Math.Sqrt((x + 12 - (xb + 6)) ^ 2 - (y + 12 - (yb + 6)) ^ 2)) * System.Math.Sin(ang))

None of the parameters even have datatypes defined.... An overflow error is usually caused by trying to force a bad value that doesnt fit into a specific datatype.

i was able to fix the problem with something else thank you though
