Syntax Error

I'm getting a syntax error on:

    Me.txtQtyOnOrder = Nz(DSum("[QTY_ORDERED]", "tblInventory", "[PART_NO] = '" & [Forms]![frmParts]![txtPART_NO] & "' AND [TRNX_TYPE] ='ORD'"), 0) - Nz(DSum("[QTY_ORDERED]", "tblInventory", "[PART_NO] = '" & [Forms]![frmParts]![txtPART_NO] & "' AND [TRNX_TYPE] = "I"), 0)

Can someone help?  I think it is at the end of the code line.

Try this. Replace the last condition with this.
[TRNX_TYPE] = 'I'"), 0)

It should probably read:
Me.txtQtyOnOrder =
Nz(DSum("[QTY_ORDERED]", "tblInventory", "[PART_NO] = '" & [Forms]![frmParts]![txtPART_NO] & "' AND [TRNX_TYPE] ='ORD'"), 0) -
Nz(DSum("[QTY_ORDERED]", "tblInventory", "[PART_NO] = '" & [Forms]![frmParts]![txtPART_NO] & "' AND [TRNX_TYPE] = 'I'"), 0)

Dim strCriteria1 as string, strCriteria2 as string

strCriteria1 =  "[PART_NO] = '" & [Forms]![frmParts]![txtPART_NO] & "' AND [TRNX_TYPE] ='ORD'"
debug.print strCriteria1
strCriteria2 = "[PART_NO] = '" & [Forms]![frmParts]![txtPART_NO] & "' AND [TRNX_TYPE] = 'I'"
debug.print strCriteria2
Me.txtQtyOnOrder = Nz(DSum("[QTY_ORDERED]", "tblInventory", strCriteria1), 0) _
                                   -  Nz(DSum("[QTY_ORDERED]", "tblInventory", strCriteria2), 0)

The problem is that you tried to wrap the "I" at the end of the 2nd DSUM with quotes.  I prefer to break this process up into steps, so I can identify the problems easily.

try changing this part

[TRNX_TYPE] = "I"), 0)


[TRNX_TYPE] = 'I'"), 0)

The last condition is closing the main quotes. Use single quotes around it.
" AND [TRN_TYPE] = 'I'"), 0)
