Text box not showing total

In my program I want to add some values together with开发者_如何转开发 a running total, and then show that total in a text box. When I try to run it, though, it just shows zero.

Here's the code I'm using

        TotalPrice = TotalPrice + Price
    Next
    TxtLuggage.Text = TotalPrice

this chunk was a part of a For next loop.

How do I fix this.

Please do not take this as an offense, but I think you should read some book or at least a decent article on .NET debugging. This one looks like an easy to spot with just a bit of basic debugging.

See this one for example, and pay special attention on stepping through code, setting breakpoints and watches

What you should do:

• set a breakpoint in the code in the problematic code line
• when debugger breaks code execution there, see which object are you changing the property for. Does this property change the text box text value? Are you using a correct form instance?
• does the For..Next loop set it to zero on its final pass?
