expanding table sumif inside an expanding table

[#1]

Hello Adobe Community,

I am new to javascript and livecycle and everything I know I have learned from youtube videos and these forums, and your help will be greatly appreciated. I have a form with two expanding tables (Table0 and Table2), Table 0 has two columns were the user can input a city name and an amount. I need Table2 to sum the amounts in Table0 that equal a city name, note that T2 expands and the code I found on the thread below doesn't work for me because I need the expanding sumif inside an expanding table (SumIf in an expanding table )

My form is in the attached link: Citysum.pdf - Google Drive

The current output (see image below) only sums the first city value in Table2. Please help!

The task isn't that simple as it sounds, as you have to performs several loops in a row to get the desired result.

Here's a script that does the job as you described it.

var aCities = [], // Array for city names
oRows = Table0.resolveNodes("Row1[*]"), // node list of input table rows
oResults, oSources, i, j, oNode, oTest, iSum,
isExisting = function (value)  { // compare function
return value === this.testValue;
};
// check every input table row to collect all entered city names
for (i = 0; i < oRows.length; i += 1) {
oNode = oRows.item(i); // create an object ot the current node
oTest = {testValue : oNode.City.rawValue}; // save its city name into a test object
if (!aCities.some(isExisting, oTest)) { // check if the same city doesn't already exists in the array of city names
aCities.push(oNode.City.rawValue); // if not add it to the array
}
}
// add as may rows in the output table as city names found in the input table
Table2._Row1.setInstances(aCities.length);
oResults = Table2.resolveNodes("Row1[*]"); // node list of output table rows
// for every city name calculate the total amount
aCities.forEach(function (cCity, iIndex) {
iSum = 0; // reset the summary
oSources = Table0.resolveNodes('Row1.[City eq "' + cCity + '"]'); // filter all rows in the input table with the current city name
// Build the total amount from the filted nodes
for (j = 0; j < oSources.length; j += 1) { //
iSum += parseInt(oSources.item(j).Amount.rawValue, 10);
}
oResults.item(iIndex).City.rawValue = cCity; // output the city name
oResults.item(iIndex).TotalAmt.rawValue = iSum; // output the total amount
});

Hi,

At line 16 add the following code

oRows = Table1.resolveNodes("Row1[*]"), // node list of input table rows 

for (i = 0; i < oRows.length; i += 1) { 

oNode = oRows.item(i); // create an object ot the current node 

oTest = {testValue : oNode.City.rawValue}; // save its city name into a test object 

if (!aCities.some(isExisting, oTest)) { // check if the same city doesn't already exists in the array of city names 

  aCities.push(oNode.City.rawValue); // if not add it to the array 

} 

}

This is the same except for the Table0 is now Table1

Then after line 31 add the following code

oSources = Table1.resolveNodes('Row1.[City eq "' + cCity + '"]'); // filter all rows in the input table with the current city name 

// Build the total amount from the filted nodes 

for (j = 0; j < oSources.length; j += 1) { // 

  iSum += parseInt(oSources.item(j).Amount.rawValue, 10); 

}

Hi Radzmar, thank you for providing an answer to my original question. Now I have another question, what if we had multiple source tables? See revised file with one additional source table Citysumv2.pdf - Google Drive

This is great, thank you so much!
