newText.type = "input";
newText.name = txt1+counter;
//newText.value = counter;

Firstly, you shouldn't assume that people will just know which templating system you are using. It looks to me like you are using the Template Toolkit, but there are many template engines for Perl.
Secondly, the template is a complete red herring here. The problem is in your Perl code. When the template can't be processed successfully, your code calls a function called ThrowTemplateError , but Perl can't find that function anywhere. Where is that function defined?
(Ok, I suppose it could look like the problem is in your template and not the code. There's some error in your template which means that TT can't process it and therefore the missing function is called. So fixing the error in your template will mean that the missing function no longer gets called. But it's still missing. And it will be a problem again the next time you accidentally break your template. So best to fix it now, I think.)
