Overflow

hi.. i have the followin codes:



<% dim counterVar
counterVar = 1%>

<% For a=0 to UBound(Action,2) %>
<% For each x in CountArray %>
((No.of actions found/total no. of alerts) * 100)
<% num = FormatNumber((( x / (rs_total("numVar"))) * 100),2)%>
<param name="val<%=counterVar%>" value="<%=(num)%>">
<% counterVar = counterVar + 1 %>
<% Next %>
<% Next %>



It will generate a piechart.. and this part is to part to get a value..
Sometimes it will get the values.. but sometimes it will have an error 'Overflow'
Any1 knows what happen?

Thanx..

It can happen if the number is too large for an integer. Try converting your numbers to CLng

o.. but this will only happens if i do not have a value...

Then put in a condition only to perform the formula when there is a vaild value.
