Simple unusual variable problem

[Bramo]

Hi guru guys,

I have serious problem. At first sight it looks very simple but i dont
have any idea how to solve it.

With this statement 'If len(rs_cit) = 0 then rs_cit = 0' I cant put
into variable 'rs_cit' value '0' if it is clean. There is no value in
html displayed.

Here is code:

....
Dim rs_customer, rs_cit, rs_total, rs_manual

i = 1
Do While Not RS.Eof

rs_customer = RS("customer")
rs_account = RS("account")
rs_cit = RS("cit")
rs_total = RS("total")
rs_manual = rs_total - rs_cit

If len(rs_cit) = 0 then rs_cit = 0
'neither this does not work: If rs_cit = "" then rs_cit = 0


response.write ("<tr>")
response.write ("<td bgcolor='black' align='right'>" & i & ".</td>")
i = i + 1
response.write ("<td bgcolor='black'>" & rs_account & "</td>")
response.write ("<td bgcolor='black'>" & rs_customer & "</td>")
response.write ("<td align='center' bgcolor='#666666'>" & rs_cit &
"</td>")
response.write ("<td align='center' bgcolor='#666666'>" & rs_manual &
"</td>")
response.write ("<td align='center' bgcolor='#666666'>" & rs_total &
"</td>")
response.write ("</tr>")
RS.MoveNext
Loop
....

rs_cit = RS("cit") might be null. In some cases using Len can be
unreliable.

Try

If IsNull(rs_cit) Or Len(rs_cit) = 0 Then rs_cit = 0

With this statement 'If len(rs_cit) = 0 then rs_cit = 0' I cant put
into variable 'rs_cit' value '0' if it is clean. There is no value in
html displayed.
...
rs_cit = RS("cit")
...
If len(rs_cit) = 0 then rs_cit = 0
'neither this does not work: If rs_cit = "" then rs_cit = 0

For what it's worth, this is all you need to meet your needs in JScript:

rs_cit = RS.Fields("cit").Value || 0


It is sufficient because JScript coerces null and empty string values into
false boolean values when used in conditional assignment constructions.
