NaN after rounding

Hi all

Using InfoPath 2007 on Forms Server 2007.

I have a data source field which is a double. I have a textbox, in which users can enter a value, and I have a rule that basically does this: ". = round(. * 10) div 10" - so basically, I multiply the value by 10, round it and divide by ten, så I am sure I only have one digit after the decimalpoint. The rounded number is used for calculations later on, so I cannot just use the display properties of the textbox to only show one decimal.

Now, what happens is that the rule seems to work just fine; If I enter "27,17" it will change quickly to "27,2" and I am happy. Trouble is that after the next post back I seem to have an NaN instead. In my example I have a button with a rule on it with an action that switches view. After the view has been switched, the "27,2" has completely disappeared and a "NaN" appears instead.

I am not sure where the error happens.But it is rather annoying. I expect it has to do with Culture somehow - the fact that Danes use comma as a decimal separator as opposed to the English notation of using the period. I do need the Danish notation, though.

Does anyone have any thoughts on this?

Thanks
