Is myPage a page object or a numeric indication of the page number? When I did something like this I had an integer variable (iPage, the page number) and a Page object (oPage, the InDesign page) that were distinct. 

It should be just a matter of making sure that the label name is correctly assigned initially and that the iFrame value that you create is identical to the appropriate box. 

A helpful tool for this sort of thing is either: 
MsgBox iFrame 
(of course if this is in a loop you'll have to Ctrl+Break to stop it from giving you a gazillion message boxes) 

or 

debug.print iFrame 
(writes the values to the immediate window) 

Either such method could tell you for sure what the labels are when they're created and when they're called. 

Chances are there's some inconsistency between the name being created when you're creating the textboxes and the one you're creating to access them.
