I couldn't note declaration of "mdectotal" ... maybe you didn't send that code but anyway let us know what is the datatype of mdectotal?

ah yeah mdectotal is
private mdectotal as decimal

its the module level variable thingy to keep adding the sales to calculate the average.

Since I don't have any experiance with the InputBox, I found the solution by adding a breakpoint to the code and stepping through the code.
The problem is that you're checking for a value of -1. When you click cancel, strInputNum equals an empty string (String.Empty). Change 'Do Until strInputNum = "-1"' to 'Do Until strInputNum = String.Empty'.
I would also suggest resetting the value of mdectotal at the beginning of the procedure; if the user doesn't click BtnClear after running the calculations previously you will get incorrect results.
Also, add a message in the InputBox to let the user know that clicking Cancel will end the input stage and allow the numbers to be calculated.
