ASP Form posting 2 decimal places 1

[Hondy]

Hi

I have a form that submits a number, how can I make sure that the user enters number that is 2 decimal places long?

if they enter 1.5 it should come through automatically as 1.50 rather than tell them to put a 0 on the end.

Thanks

You can use the FormatNumber() function on the value you read in from the form.

Um, have tried it but I don't know how to apply it. I mean I know the syntax but I don't know how to apply it

do I apply it on the form variable or the string?

e.g.
on the form
<input name="form_number" value= "" type="text" size="4" maxlength="4" />

or in the code
mydecimalnumber = Request.Querystring("form_number")

Where and how do I put the format number?

Cheers

ah fixed it (mydecimalnumber is a string)


mydecimalnumber = formatnumber (mydecimalnumber)

Actually,

mydecimalnumber = FormatNumber(mydecimalnumber, 2)
