@DTW_SUBTRACT Question

Hi list!

I have this @DTW_SUBTRACT function that is blowing up wit hthe message: NET.DATA
Error: Function call to DTW_SUBTRACT failed. Error Number is 4001.  Obviously,
this is the message when one of the parameters is not a number.  I am printing
V3 and V4 and they are displayed as a number.  The last statement of this code
is the one that explodes.  In this case, BUDGET is "0" and the expenses is
"5,519-", but I can't substract the BUDGET from the DISBURSEone.   Before
calling the SQL1 function, I am executing @DTW_ASSIGN(DTW_EDIT_CODES,"  JJJJ")
to format the fields.  That is why the expenses amount has a format with commas
in it.

Please check these code and see if I am skipping something...

%FUNCTION(DTW_SQL) sql1(OUT t1) {
SELECT DEPARTMENT, DEPTNAME, INTEGER(SUM(BUDGET)), INTEGER(SUM(DISBURSE))
FROM $(library).XDBUDGT
WHERE RECORDTYPE = '$(ptd)' AND FISYEAR = $(syr) AND FISQTR <= $(fqtr)
$(locwhere)
GROUP BY DEPARTMENT, DEPTNAME
ORDER BY DEPARTMENT, DEPTNAME
%REPORT {
<center>
  <table border=3>
    <tr>
     <th>Dept</th>
     <th>Description</th>
     <th>Budget</th>
     <th>Expenses</th>
     <th>Variance<br>Over/<font color="red">Under</font><br>Budget<br>$(rt)</th>
     <th>Percent<br>Over/<font color="red">Under</font><br>Budget<br>$(rt)</th>
    </tr>
%ROW {

     </td>
     <td>
      %if ($(V2) == "")
        &nbsp;
      %else
        <small>$(V2)</small>
      %endif
     </td>
     <td align=right>$(V3)</td>
     <td align=right>$(V4)</td>
     <td align=right>
        @dtw_subtract($(V4), $(V3), vary)
