Please help with instanceManager

I published a sample of my work which will better explain the issue I am having with the 2nd subform.

https://acrobat.com/#d=8pJfPJ-FjLaxfvWvNJ6H2Q

Please explain a bit more. How is an instance of the 2nd subform added? You say it's based on a value in the 1st repeated subforms. Does each 2nd subform depend on a particular 1st subform? Just list the sequence of actions that take place.

Thanks for the reply. I think the sequence would go like this......

\\The below script is in a button click. It controls both Subforms. (I labeled them Subform1 & Subform2). The dropdown box value controls whether the second Subform is added.var nSubLength = Form1.nodes.length;
var nSubLength = Form2.nodes.length;

var nNumSub = 0;

for (var nCount = 0; nCount < nSubLength; nCount ++) {if (Form1.nodes.item(nCount).className == "subform")
if (Form2.nodes.item(nCount).className == "subform") {
nNumSub = nNumSub + 1;
}
}
if (nNumSub == 10) {
xfa.host.messageBox("The maximum allowable number of subforms is 10. You cannot add any more subforms.", "Warning", 3);
}
if (Form1.Subform1.DropDownBox.rawValue == 1) {
Form1.Subform1.instanceManager.addInstance(1);
Form2.Subform2.instanceManager.addInstance(1);
}else {
Form1.Subform1.instanceManager.addInstance(1);
}\\The textbox in Form2.Subform2 is calculated. the script is............

if (Page1.Data1.Data.Principal.rawValue == 1) {
this.rawValue = Page1.Data1.Data.Name.rawValue;
}
else {
"";
}

There are several issues with this script.

1. nSubLength is declared and acquired twice. Is this varialble and loop an attempt to find the number of repeated subforms in subform 1 or 2? If it is then there is a much easier method. The instance manager keeps track of the number of instances.

For example: Form1.Subform1.instanceManager.count

The maximum allowed is also a property of the instance manager.

Form1.Subform1.instanceManager.max


2. The line that tests the drop down

if (Form1.Subform1.DropDownBox.rawValue == 1) {

only references the first repeated subform. Is this your intention?

Good. I like easier ways. I did set a max in my example, but it is not needed. So, with that said. the button will have the script...

Form1.Subform1.instanceManager.addInstance();
Form2.Subform2.instanceManager.addInstance();


So that is the easy part. To answer the 2nd part....regarding the 1st reference only - that is not my intention. (the main problem I am having really) My intention is to add an instance to the second subform anytime "yes" is selected. whether every other time, everytime, or not at all.

So the First Subform could have 6 instances and the 2nd subform could have 3.

Does that make any sense?

I do understand when you you said my script only referenced the 1st instance...not what I wanted.

If you want the selection of a "Yes" from the dropdown to create a new instance of the second subform, then put the addInstance on the change event of the dropdown field.

Do you also want to remove an instance of the second subform if the selection is changed to "No"?

That wouldn't work for 2 reasons. 1. If I have 6 instances in the first subform and only 2 yes values selected, the rest would be no therefore removing the 2 instances i need in the 2nd subform. #2. If I add an instance on yes. that would add a subform so no showing would be instance 0 & 1, but I only need 0 at this point.I know. the project I am working on is from a specific design I have to work around. I wouldn't set it up like this if I had my way.

In subform1, and instance is always added. In subform2 an instance is only added when "yes" is selected. if "no" is selected. Subform2 does nothing. However, the next instance in the subform1 could be "yes", thus adding another to the 2nd subform.

I thought.. (if) "yes" then add subform2 & subform1 (after clicking the "add" button (else) "no" then only add to subform1 (after clicking the "add" button)I just don't know the right script to use that can add the instances the way I want to.

I have a form that uses instancemanager with addinstance to add rows of a table. I have a button that looks at the raw data value of a field, within that table, and uses it to populate the "To:" field in MS Outlook.
My problem is that this will work with the field in the first row but not the second row.

How can I make this work?

Thanks.
