Specific VBA Calc.

Hi Forum,

Maybe a simple question but I still need some help with a formula clarification:

Could somebody help me with this:

TempCalc = CInt(TextBox3.Value) * (16*POWER(SQRT(CInt(TextBox1.Value)*(1-CInt(Textbox1.Value)))/(CInt(TextBox1.Value)*CInt(TextBox2.Value);2))

what is wrong?

Thanks in advance
