A string is an array so you can do 

For(int I = 0; I < Len(Str); +i)
{
	var ThisChar = Str[i];
if (ThisChar == "1")
	...
}


or something like that

Currently in my javascript strValue stores the values of all the titles
such 
as "12356"

strValue = strValue +
document.frmMemberDetails.cboTitle.options[i].value;

is there a way to do somthing like this....

---------->
string= "12345"

read string one by one

if string has "1" then
	check if string has "2" or "3" or "4" or "5" or "6" or "7" or
"8" or "9"
		alert "can have only one thing"
<-----------

how can i read a string one by one...any way to do that??

Thanks Iain for your help..although it's bit hard to do taht way..do you

have any suggestions for the above..?
