  if CurPageID = iscustompage1.id then
    starttimer(WizardForm.Handle,WizardForm.NEXTBUTTON.Handle,'Next',5)
  else

To localize a string for Pascal Script, define a custom message in the language file:

[CustomMessages]
NextButtonCaption=Next

And then use this custom message using the CustomMessage function function in your code:

starttimer(
  WizardForm.Handle, WizardForm.NEXTBUTTON.Handle, 
  CustomMessage('NextButtonCaption'), 5)
