Approval Procedure to change the price of items

Question

Hi!
i 'm trying to create a query to an Approval Procedure to change the unit price in the Purchase Order  i create this query:
SELECT DISTINCT 'True' FROM POR1 T0 INNER JOIN OITM T1 ON T0.[ItemCode] = T1.[ItemCode] WHERE T1.[ItemCode] = $[$38.1.0] AND T1.[LastPurPrc] <> $[$38.14.0]
as you see this query compare is the Last Purchase Price is different than the actual unit price, and these for each line of item.
I think this is correct, and i configure the Approval Procedure, but when i check the AP in the Purchase Order changing the Unit Price, it gets me an error that says
1) [Microsoft][SQL Native Client][SQL Server] Error converting data type nvarchar to numeric.
What happend?
Am i doing something wrong ?
In easy term, i just want to execute an approval procedure when the user change the unit price in the purchase order.
Hope you can help me !
Thanks in Advance
Best Regards !

Xavier,
maybe you are with a problem thar you dont' know, i can to expain this point,
1. if you want one approval at level line (comparing prices), not possible to make this way the approval, because you don't have control at level line while the document isn't in database.
2. i bealeve that the better way is to make a store procedure for to insert each record into temp table while to add line in purchase order without (formatead seaches), now, when you create a purchase orden you need create a query for to search record in the temporal table with the condicion that you needed.
3. now, if you want to call a value on the screen (money), the better way is $[$38.1.number]
Good look,
