//DsrEditBox is the function written for the text boxes to check if the correct values as specified are entered or not
//the parameters for the function are
// 1)input name is the name given for the textbox in the HTML Doc
// 2)reqname is the name to be displayed in the output alert messages 
//   for ex:message is"Invalid First Name!please check atlest one checkbox" then reqname is "First Name"
// 3)compulsory == compulsory if the field is compulsory in the form
// 4) type is the required type given by the user
//    for ex: if the user needs the validations for alphabets(both cases) then type = alphabet
//			  if the user needs the validations for alphanumeric then type = alphanum
//			  if the user needs the validations for alphabets and dot only then type = alpha.
//			  if the user needs the validations for alphabets,spaces and dot then type = alphasp.
//			  if the user needs the validations for alphabets,numbers,spaces and dot then type = alphanumsp.					
//			  if the user needs the validations for company Name then type = companyname
//			  if the user needs the validations for product name then type = productname
//			  if the user needs the validations for productid then type = productid
//			  if the user needs the validations for number then type = number( "+"  is notallowed here)
//			  if the user needs the validations for  positive integers then type = posinteger("+" is allowed here)					
//			  if the user needs the validations for integers(both positive and negative) then type = integer
//			  if the user needs the validations for positive Decimal numbers(user can enter "+" before number) then type = posdecimalnumber					
//			  if the user needs the validations for Decimal numbers(user can enter "+" and "-" before number) then type = negdecimalnumber
//			  if the user needs the validations for fax then type = fax					
//			  if the user needs the validations for phone then type = phone
//			  if the user needs the validations for email then type = email
