Question

        //Take value from xTextBoxTotal and store it


        Double Total = Convert.ToDouble(XButtonTotal.Text);


       //Take value from xTextBoxRecieved and store it
        double Recieved = Convert.ToDouble(xTextBoxRecieved.Text);

       //Take value from xTextBoxTotal and subtract from amout recieved
        double Amount = Total - Recieved;

        //Take the Amount and store it in xTextBoxReturn
        xTextBoxReturn.Text = Amount.ToString("C");

The xTexBoxTotal is in a currency format, Same as the XTextBoxReturn.Text.

The error I get when it gets to the xTextBolTotal is :

Double Total = Convert.ToDouble(XButtonTotal.Text); in yellow.

I assume I need to get the command that strips out the $, I thought that the convert.todouble did that.

Any help is apperciated.

I believe you would need to use a NumberStyles define to allow this, something like

Convert.ToDouble(xTextBoxRecieved.Text, System.Globalization.NumberStyles.AllowCurrencySymbol);

You may need more than that, this should help
