I'm trying to use multiple instr with else if but I think its only working on the first one. I have a  customer memo code with some sales Brand restrictions and this one that catches third party restrictions. It also catches other stuff like no export and stock level. Any help would be great : )

if {SO_SalesOrderDetail.UDF_RESTRICT} like "*5*" then
if instr({AR_CustomerMemo.MemoText},"NoFulfillment") > 0
then "NoFulfillment"

else if {SO_SalesOrderDetail.UDF_RESTRICT} like "*4*" then
if instr({AR_CustomerMemo.MemoText},"WalMart") > 0
then "NoWalMartSales"

else if {SO_SalesOrderDetail.UDF_RESTRICT} like "*3*" then
if instr({AR_CustomerMemo.MemoText},"Ebay") > 0
then "NoEbaySales"

else if {SO_SalesOrderDetail.UDF_RESTRICT} like "*2*" then
if instr({AR_CustomerMemo.MemoText},"Amazon") > 0
then "NoAmazonSales"

else if {SO_SalesOrderDetail.UDF_RESTRICT} like "*1*" then
if instr({AR_CustomerMemo.MemoText},"NoThirdParty") > 0
then "NoThirdParty"

fyi this is the customer memo code
