[R] Widget inserts NA instead of entered data

I am relatively new to R and extremely new to widgets.  Any help would 
be greatly appreciated!  The script below is a portion of a larger 
script in which the user has entered the number of files representing 
their transcription factor (in this case 2) and their control (again 
2).  In this portion, I would like the user to indicate which files 
(from 1-4, in this case) are transcription factor data (1 and 2) and 
which are control (3 and 4).  The problem is that whenever I run the 
script and enter "1" and "2"  and "3" and "4"in the widget boxes, the 
values returned at "NA" and "2" and "NA" and "4".  Does anyone know why 
the first values are being returned as NA?  Any ideas on how to fix 
this?  I am using R 2.2.1 on Windows XP Pro.  Thanks!


PWEnv<-new.env(hash=TRUE, parent=parent.frame(1))   
entry2<- entryBox(wName = "entry2", wValue= "", wEnv=PWEnv)
entry3<- entryBox(wName = "entry3", wValue="", wEnv=PWEnv)
label4<-label(wName="label4", wValue="Please enter the number for one of 
the _635 files that
represent your transcription factor.", wEnv=PWEnv)
label5<-label(wName="label5", wValue="Please enter the number for one of 
the _635 files that
represent your controls.", wEnv=PWEnv)

for (i in 1:tf.count.2){
pWidgets<-list(topRow=list(label4=label4), textRow=list(entry2=entry2))
aWidget<-widget(wTitle="Assign Experimental Files", pWidgets, env=PWEnv)

for (i in 1:ctrl.count.2){
pWidgets<-list(topRow=list(label5=label5), textRow=list(entry3=entry3))
aWidget<-widget(wTitle="Assign Control Files", pWidgets, env=PWEnv)

 > ctrl
[1] NA  "4"
 > tf
[1] NA  "2"
