greater than or less than when numeric

[camillaj]

I'm very new to ASP and VB, but this doesn't make sense to me at all.

I'm checking whether a value is greater than an other, i.e.

If questNr > Session("LastAdded&quot Then
..do something
Session("LastAdded&quot = questNr
End If

This works fine until questNr is '10' and lastAdded is '9'. Then it says that questNr (10) is les than lastAdded (9). I write these values out to the screen, so I know that for sure.

How can 10 be less than 9? I guess this mayhave something to do with the datatype. questNr is just a number I retrieve from Request.Form("questNr&quot

Thanks

All the built-in ASP objects return STRINGs as a general rule - that's Session, Request etc etc.

So if you want to compare them to a number, you need to explicitly convert them to a number. Otherwise they get compared alphabetically: "100" gets filed before "9" in the phonebook (if they were business names).

To convert: try CInt() or CDbl() or whatever suits.

Good luck

yep this must work...
If cint(questNr) > cint(Session("LastAdded&quot) Then
..do something
Session("LastAdded&quot = questNr
End If
