For the aid of other poor souls that have this problem, I will post what the problem actually is, and possible ways to solve it....though I'm not convinced the developmentor site is actually going at the moment.
System.FormatException: Input string was not in a correct format. at System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal) at System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info) at System.Int32.Parse(String s) The problem is related to System.Globalization.CultureInfo as Paul van Brenk said.....and specifically (in this case, and others I've since found on the internet) to the value of "NumberFormat.PositiveSign".... for us this was set to "1" on random machines ! (other examples I have seen reported are set to "0").....which I assume meant that StringToNumber would read "1" as "+" and then complain it didn't make sense....the value is associated to the users regional settings, and though the user can access "NegativeSign" through control panel, it appears that they cannot access "PositiveSign".....why anything or anyone has set this I don't know...I can only assume it is some sort of virus.....I think it only affects .net v2.0...but that's a guess...it seems a very easy way to break lots of .net apps, sometimes in quite subtle manners. You can fix it by (Paul van Brenk) explicitly setting the culture....which seems very sensible....(obviously there are times when you want to interpret in the local culture, and then you are at the mercy of that local culture settings). Int32.Parse( "1", System.Globalization.CultureInfo.InvariantCulture ); You can fix also by setting HKEY_CURRENT_USER\Control Panel\International\ PositiveSign (I think that's right) to blank...or whatever seems sensible.

I don't recall. I think I may have done something horrific like change the type of the database field.
