Prepopulating form checkboxes..
Hi I've got a bunch of string values in a session variable that I want to split into an array and use to conditionally 'check' some checkboxes.

My VbScript..
Code:
<%
' // Session("merchantCards") contains a dynamic array of values like "MC,VISA,BC"
cardArray = Split(Session("merchantCards"),",")

for i = LBound(cardArray) to UBound(cardArray)
	currentCardType = ""
	response.write "&nbsp;" & i & " = " & cardArray(i) & "<br>"
		if CStr(cardArray(i)) = CStr("MC") then
			valueMC = "checked"
		elseif CStr(cardArray(i)) = CStr("Diners") then			
			valueDiners = "checked"
		elseif CStr(cardArray(i)) = CStr("VISA") then			
			valueVISA = "checked"
		elseif CStr(cardArray(i)) = CStr("AMEX") then			
			valueAMEX = "checked"
		elseif CStr(cardArray(i)) = CStr("BC") then			
			valueBC = "checked"
		elseif CStr(cardArray(i)) = CStr("JCB") then			
			valueJCB = "checked"
		end if
next
%>


I then want to use the 'valueXXX' (eg: valueMC = "checked") string to pre-check some check boxes...

Code:
<table width="100%" border="0" cellpadding="0" bgcolor="#EEEEEE">
          <tr> 
            <td width="6%"><input type="checkbox" name="merchantCard" value="MC" <%= valueMC %> ></td>
            <td width="34%">MasterCard</td>
            <td width="4%">&nbsp;&nbsp;&nbsp;</td>
            <td width="3%"><input type="checkbox" name="merchantCard" value="Diners" <%= valueDiners %>></td>
            <td width="53%">Diners Club</td>
          </tr>
          <tr> 
            <td><input type="checkbox" name="merchantCard" value="VISA" <%= valueVISA %>></td>
            <td>VISA</td>
            <td>&nbsp;</td>
            <td><input type="checkbox" name="merchantCard" value="AMEX" <%= valueAMEX %>></td>
            <td>American Express</td>
          </tr>
          <tr> 
            <td><input type="checkbox" name="merchantCard" value="BC" <%= valueBC %>></td>
            <td>BankCard</td>
            <td>&nbsp;</td>
            <td><input type="checkbox" name="merchantCard" value="JCB" <%= valueJCB %>></td>
            <td>JCB</td>
          </tr>
</table>


What I'm finding is the 'for' loop does the right thing, that is, it loops through each value in the array, but my 'if' statement seems to execute once and drop out, that is, it only sets the first "checked" value it finds and not the rest (if there's multiple values selected in the form)

Any ideas on what I'm doing wrong?

Ta,
Jb.

the way you have nested your If statements means as soon as one is true, it skips the rest, because of the "else". try making them all separate "if"s, so it will skip all that do not apply, but will execute all that do

thanks, but I've tried that!

Code:

for i = counter to UBound(cardArray)
	response.write "&nbsp;" & i & " = " & CStr(cardArray(i)) & "&nbsp;" & "<br>"
	cardString = CStr(cardArray(i))
		if cardString = CStr("MC") then
			output = cardArray(i)
			valueMC = "checked"
		end if
		if cardString = CStr("Diners") then
			output = cardArray(i)
			valueDiners = "checked"
		end if
		if cardString = CStr("VISA") then
			output = cardArray(i)
			valueVISA = "checked"
		end if
		if cardString = CStr("AMEX") then
			output = cardArray(i)
			valueAMEX = "checked"
		end if
		if cardString = CStr("BC") then
			output = cardArray(i)
			valueBC = "checked"
		end if
		if cardString = CStr("JCB") then
			output = cardArray(i)
			valueJCB = "checked"
		end if
	cardString = ""
next

I'm stumped! I've tried everything from passing the current array value into an external function to changing the if to a case statement (which would function exactly as you've described) but to no avail!

Jb.

Did you get it to work??
I was browsing through the forums because of a similar problem and was just wondering if you ever solved the problem. I too have tried everything and can't seem to get it to work. If you did figure it out, would you mind sharing??

Thanks much.
