Move Lines from One table to another based on Row Number

I am building a system where I fill a PO table based on a Req table where the end user indicates which rows of the Req table they would like to have on the PO.

I cannot get the advanced matchcode system to pull only the row indicated by my GV. I have tried using the system row number and another column I created just for line numbers but the expression is similar: DW_REQ_TABLE[SYS_ROW_NUMBER]_S = GV_Current_Line_ . Both fields are numeric.

The system will pull the whole table just fine without the matchcode but will not pull just the one row on each loop.

Anyone have any ideas?
