Seems your are already done with your project. Sorry for the late response, Ive been unable to get back in a timely manner.

Just for your understanding I wanted to point out a few mistakess. First you dont need a double (pun) conversion; you dont need to convert first to a double and then to a decimal. Converting straight to the datatype you want is fine. Second with the Decimal.TryParse method you dont need to convert (cdec()) to a decimal, it will automatically do that for you.

The TryParse has two purposes, first it will automatically convert your value into the variable you provide and second it will return a true/false answer whether it was successfull or not. Lastly you wouldnt want to use Decimal.TryParse to store a value into a datatype of double, in that case either change the variable datatype to a decimal or use a Double.TryParse.

Thank you, Tom. I have three more programs to write. I am reading about class and objects. I used and object (Me.) and TextBox1 as property for the first assignment. Now, I am working in program 2 of the assignment.

Thanks again
