Hello all -
I have done ASP for a while but never found a quick way to handle
this issue.
I have 8 dropdown boxes. Is there an easy to check that only 1 has
selected 'Yes' and the others are 'No' without checking infinite
combinations?
I usually do this with alot of coding for the combinations.
Any thoughts are appreciated.

Dropdowns with only two choices? Why not radio buttons?
Assuming you've given them names to make them easily distinguishable from
the rest of the data elements in your form (say: dd1,...dd8), you can simply
loop through them. Something like this:
function OnlyOneYes()
dim i,curval, newval, bResult
curval="No"
bResult=true
for i=1 to 8
newval=request.form("dd" & i)
if newval = "Yes" then
if curVal = "Yes" then
bResult=false
exit for
else
curVal = newVal
end if
next
if curval = "Yes" then
OnlyOneYes=bResult
else
OnlyOneYes=false
end if
end function
