Problems deleting last row of table

Question

I have tried a number of examples to make a button delete the LAST row of a table, but I cannot make it.
This is the script I am currently using, but it only delets the second row. I'm desperate, I don't know where's the mistake. Please help!
var sSubformSOM = "xfa.form.Summary.INTrack.INRecordTable.INRecord.Row1";
var bCalc = true;
var message = "You have reached the maximum number of items allowed.";
var oSubform = xfa.resolveNode(sSubformSOM);
var sParentSOM = oSubform.parent.somExpression;
var sManagerSOM = sParentSOM + "._" + oSubform.name;
var oManager = xfa.resolveNode(sManagerSOM);
var nMinCount = oManager.occur.min;
var nSubCount = oManager.count;
if (nSubCount > nMinCount) {
          oManager.removeInstance(1);
          if (bCalc == true) {
                    xfa.form.recalculate(1);
} else {
          xfa.host.messageBox(message,"Remove Item", 3);

Hi
In fact what you want is somehow strange. But this may be used.
For the first row:
<b>SELECT * FROM <table_name> UP TO 1 ROWS
INTO gs_record</b>
<i>*-- If you want you can use <b>"ORDER"</b> statement here to order *the contents</i><b>.</b>
For the last row:
As far as I know, You should select all the records till the last row and then get the last row.
But, I think without ordering it will be somehow weird. We do not deal how the database layer handles order of the table. It has different policies regarding indexes etc... If you have an ordering condition, I think it will often be more convenient using an internal table to handle data. That is, retrieve your data with SELECT statement into an internal table, sort it and read it.
