Javascript code error depending on Adobe Reader Version

Question

Hi everybody,
I develop a Adobe interactive forms with ALD version 8 on ECC 6.0 system .My forms is only used in offline scenario ( thru e-mail) .My form is set as compatible with Adobe Reader 7.0.5
In the form i got 2 different tables .
The first table , let's call it Tab1 , is define as follow :
  Field 1 -> DropDowlist box
  Field 2 -> TExt Field
  Field 3 -> DropDownlist Box
  Field 4 -> DropDownlist Box
  Field 5 to 11 -> Text Field.
The second table, let's call TAB2 , is define as follow :
  Field 1 -> DropDownlist box
  Field 2 -> Text Field
  Field 3 -> Dropdownlist box
  Field 4 to 10 -> Text Field.
The content of the DropDownlist of Field1 of Tab1 and Tab2 are similar.
When user try to click on Field 5/6/7/8/9/10/11 of Tab1 for populate it, i wrote a javascript code to check if Field3 is populate. If not i set a focus on Filed3 of Tab 3 .
Same check have been written for Tab2 when user try to click on Field 4/5/6/7/8/9/10.
This code works fine with Adobe REader 8.1 but with Adobe Reader 7.0.9 it doesn't work and that's a main issue because it can't be possible to be sure that all user will use adobe Reader 8.1.
Adboe Reader 7.0.9 is a pre-requisite as describe in OSS note 834573.
Does somebody face the same problem and can help me to solve it .
Regards
Ps : Here is the javascript i wrote :
var pos = eval(this.parent.index);
if (xfa.resolveNode("data...ACTIVITY_DETAIL["+pos+"].SOFTWARE").isNull)
xfa.host.setFocus(xfa.resolveNode("data...ACTIVITY_DETAIL["+pos+"].SOFTWARE"));

Hi Juergen,
I check this code with Adobe Reader 7.0.9 and 7.1 and that doesn't works.
With Adobe Reader 8.1 that works .
I don't test it with Adobe Reader 9.0 , does this version support by Adobe forms in SAP ??
My main problem is that a lot of user will use this forms . Some of them will use their own computer but some of them will use others company computer so i can't be sure that Adobe reader will be 8.1 and my customer want that test working with Adobe Reader 7.0.9 which is regarding oss note the minimum version for Adobe Interactive forms.
Thanks.
