Sum webpage fields

[MARELUAD]

How can I sum of two fields in a webpage

I have tried:

<script language="VBScript" >
function somautokm()
Dim i
i = form1.km1.value + form1.km2.value
form1.totaalkm.value = i
end function
</script>

But I get by 22+33 = 2233 ?????

Hello MARELUAD,

Common behavior of variable type of string taken as number.

i = cint(form1.km1.value) + cint(form1.km2.value)

There are also cint(), cdbl(), csgn() etc. Choose the proper one.

Correction:

I meant:
There are also cint(), cdbl(), [red]csng()[/red] etc.

Sure also clng(), ccur() etc.

I have tried it but I get the next error:
Type mismatch: 'cint'

MARELUAD,

Insert this this see what you get
msgbox form.km1.value & vbcrlf & _
vartype(form.km1.value) & vbcrlf & _
escape(form.km1.value) & vbcrlf & _
len(form.km1.value)

(If either one of the function provokes error, take it out until msgbox gives you at least some info.) Post the output.

I get with 22 the next results:
22
8
22
2

MARELUAD,

The result shows that, at least, km1 is normal. Try the same for km2. Look, with due respect, put
i=cint("22")+cint("33")
instead, what do you say form1.totaalkm.value will show?
