Using Numeric Data Collected From Forms

Hello,

I'm having a problem using a numeric data element submitted by my form. I'm checking for a numeric value, but it seems to be coming in blank. Is it necessary to convert the item to an integer?

*** This code doesn't work - Num_PPAC form item sets TNT:
If ((Request("Num_PPAC") <> "") And (isnumeric(Request("Num_PPAC")))) Then

TNT = CInt(Num_PPAC)

ReDim Temp_PPADCode(TNT)

If Request("GenCodes") <> "" Then
X = 1
Do while X <= TNT
RandStuff = RndStr(7,"123456789abcdefghijkmnpqrstuvwxyz")
Temp_PPADCode(X) = Request("PPAC_PREFIX") & RandStuff
X = X + 1
Loop
pMsg = "TNT&nbsp;=&nbsp;" & TNT
Session("STemp_PPADCode") = Temp_PPADCode

End If

*** This code does work - TNT set to 10:
If ((Request("Num_PPAC") <> "") And (isnumeric(Request("Num_PPAC")))) Then

TNT = 10

ReDim Temp_PPADCode(TNT)

If Request("GenCodes") <> "" Then
X = 1
Do while X <= TNT
RandStuff = RndStr(7,"123456789abcdefghijkmnpqrstuvwxyz")
Temp_PPADCode(X) = Request("PPAC_PREFIX") & RandStuff
X = X + 1
Loop
pMsg = "TNT&nbsp;=&nbsp;" & TNT
Session("STemp_PPADCode") = Temp_PPADCode

End If


Thanks.

this is a javascript forum and not an ASP forum. you should have posted in the right forum. :rolleyes:
Anyway, here's the answer.

if the item you request is used many times, it is advisable to put it in a variable. And it is also more efficient if you specify what request collection you are accessing rather than just specifying Request(item)

dim ppac
ppac = Request.Form("Num_PPAC") 'if method is POST
'ppac = Request.Querystring("Num_PPAC") 'if method is GET
If ppac <> "" And isnumeric(ppac) Then

TNT = CInt(ppac)
...

Hey Glenn,

I just wanted to say thanks for your help, and to let you know that now my code is working fine, plus I've learned more about ASP and forms.
