>>>OK, I've created a log and verified that my calculations are correct. But the text box does not show the correct value, although my log shows that it has the correct value!

>>To add to Viv's questions:
>>
>>- it looks like you have a "Base Premium" of $102.87 and a "Rider Premium" of $1.35, which are added to get a "Total Premium" of $104.22. However, it looks like you have only 2 controls on the screen. Do you want/need to show all 3 values? Is it possible the top control shows the base premium first, then gets updated later when a rider premium (if any) is calculated? Maybe there's a .Refresh() call of some type that's being missed.

>Your arithmetic is correct, but no I don't need to show all three values, just the total value and the rider values. The weird thing is that it works perfectly at my site, but not at their's.

Is this standard ASP.NET or is it using MM.NET? If it is standard ASP.NET you could send me the relevant aspx and .vb/.cs files I may be able to help.
