Status: offline 		Sorry for such a newbie question!!

I have a form which gets a value on a page once this form is submitted I create a session variable on my next page


I then want to do some calculations on that number. Do I have to do anything like casting this string value to an integer? If so how do i do this


I thought this would work but doesnt


      

Could you advise how this is done please

Status: offline 		Sometimes you can store a form value in session and it will work, but as you suggested, casting is usually good before doing calc's.  With something like using the variable in a query string it doesn't matter because the query is a text string....but going the other way is tougher.  Reading a value from a form that comes back as 5 may not be the same on a compare when you match it with a database integer value of 5 ... until you do the casting.

That can be done with something like
yournum = CInt(Request.Form("thefield")) or yournum = CLng(Request.form("thefield"))

I have a function I use for doing that because sometimes you get burned with nulls, empty strings, etc.  Function checks for numeric and passes back 0 if it fails; otherwise does the cast into a Long Integer.  You'll probably find having that in some kind of core library would be helpful!


Good luck!
