What is wrong with this syntax?

=DSum("[QTY_ORDERED]","tblInventory","[PART_NO] = '" & [Forms]![frmParts]![txtPART_NO] & "' AND [TRNX_TYPE] in ('I','O')")+DSum("[QTY_ORDERED]","tblInventory","[PART_NO] = '" & [Forms]![frmParts]![txtPART_NO] & "' AND [DATE_RECD] <> "")

"" is a Zero Length String (ZLS) which is not the same as null.  Since ZLS can only occur in a string data type, it is unlikely that your date received is a ZLS.  It is almost certainly null if it is "empty".
 =DSum("[QTY_ORDERED]","tblInventory","[PART_NO] = '" & [Forms]![frmParts]![txtPART_NO] & "' AND [TRNX_TYPE] in ('I','O')")+DSum("[QTY_ORDERED]","tblInventory","[PART_NO] = '" & [Forms]![frmParts]![txtPART_NO] & "' AND [DATE_RECD] Is Not Null)

The first part works ok.  But the 2nd part:

=DSum("[QTY_ORDERED]","tblInventory","[PART_NO] = '" & [Forms]![frmParts]![txtPART_NO] & "' AND [DATE_RECD] Is Not Null)

If I paste it without the 1st part gives me a syntaz error.

Looks like it is missing the final "

...   Is Not Null")

Final is:

=DSum("[QTY_ORDERED]","tblInventory","[PART_NO] = '" & [Forms]![frmParts]![txtPART_NO] & "' AND [TRNX_TYPE] in ('I','O')")+DSum("[QTY_ORDERED]","tblInventory","[PART_NO] = '" & [Forms]![frmParts]![txtPART_NO] & "' AND [DATE_RECD] Is Not Null")


Thank You!
