Add instance help

Question

I'm trying to create a document that has 4 seperate tables in that the user will enter information for various materials.  I have created a button to add another row in each of the 4 tables using the following JavaScript code:
frmCredit4._Item.addInstance(1);
frmCredit5._Item.addInstance(1);
frmCredit6._Item.addInstance(1);
frmCredit7._Item.addInstance(1);
xfa.form.recalculate(true);
All of the works fine so far, but I need to have the first column repeat in each of the 4 tables, which is where I get stuck.  I tried setting the binding to global, but that makes whatever was entered in the first row of the first table repeat in all of the other rows of all of the tables, which of course won't work because I need different data in each of the rows of the first column.  Any suggestions?
Thanks,
Michael

Your requirement is tricky and very challenging (I like the stuff). Check the attachment here is what I have done.........
1. Set the Binding to Normal
2. Added FormCalc code to the "exit" event of the Table1:Column1:txtMaterialComp
Here is the script
var partLeft
var partRight
partLeft = Substr($.somExpression, 1, 69)  //69 is the length of the characters before '5' in the SOMexpression of the field
partRight = Substr($.somExpression, 71, 200)  //71 is the starting position for the right part and 200 is to get the chars till the end....or you can have 500
//xfa.host.messageBox(Concat(partLeft,5,partRight))
var transferTo5
transferTo5 = Concat(partLeft,5,partRight," = ", """", $.rawValue, """")
//xfa.host.messageBox(transferTo5)
eval(transferTo5)
This script will dynamically access the instance number and then sets the value in the specified relative field.
Hope you can take it from here and add additional script to populate rest of the tables as you need.
Good luck,
