can someone help me with a homework question?
i know that is a huge long shot cause it's programming help over the net.....i'm gonna try to explain it the best i can...

if so...


i'm a second semester, first year programmer in college...so cut some slack if i sound stuipd?? haha, i'm gong for networkin' but i HAVE to take programming the first year for basic programming requirments and it's not going all that well...

i'm makin' a window's application that will calculate a pay check..it figurs out the CPP, Income Tax and Net Pay when you put in the hourly rate and hours worked.
we are using seperate funcions for each calculation (income tax, cpp..etc)
i've got everything done and working except for the net pay.
every time i try to put a formula in that it hink works it doesn't and give me that god **** blue underline!!!!!

here's my code:

Private Function GrossPay(ByVal snghoursworked As Single, ByVal sngrateofpay As Single) As Single
Dim sngtotal As Single

sngtotal = snghoursworked * sngrateofpay
Return sngtotal
End Function

Private Function CalcIncomeTax(ByVal snggrosspay As Single) As Single
Dim sngincometaxdeduct As Single

sngincometaxdeduct = snggrosspay * 0.2
Return sngincometaxdeduct
End Function

Private Function CalcCPP(ByVal snggrosspay As Single) As Single
Dim sngcppdeduct As Single

sngcppdeduct = snggrosspay * 0.1
Return sngcppdeduct
End Function

Private Function CalcNetPay(ByVal snggrosspay As Single, ByVal sngincometaxdeduct As Single, ByVal sngcppdeduct As Single, ByVal sngdisplaygrosspay As Single) As Single

sngdisplaygrosspay = snggrosspay - (sngincometaxdeduct + sngcppdeduct)
Return sngdisplaygrosspay
End Function

Private Sub btnCalcNetPay_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalcNetPay.Click
Dim sngGrossPay As Single


sngGrossPay = txtHoursWorked.Text * txtRateofPay.Text
lblGrossPay.Text = Convert.ToString(sngGrossPay)


lblIncomeTax.Text = Convert.ToString(CalcIncomeTax(sngGrossPay))
lblCPP.Text = Convert.ToString(CalcCPP(sngGrossPay))
lblNetPay.Text =




End Sub
End Class

???


forgot to mention option strict off

ugh....oh well......

why are you converting to string and not integer? or, if needed, long? also (this is via cimbasic) have you tried assigning the text box a variable and set the variable of the text box to its value when a expression is updates, say the button calc is pushed (they'll need to be public variables)
