Why are both validation and accessibility tools showing duplicate id's

Hi,

I'm testing a website and both my accessibility tools and page validation are saying the page has duplicate ids. However when I look at the code the all look unique to me. Here are just a few examples from W3 page validation:

' Duplicate ID gform_wrapper_5.
' Duplicate ID gform_5.
' Duplicate ID gform_fields_5.
' Duplicate ID field_5_1.
' Duplicate ID input_5_1.
' Duplicate ID field_5_2.
' Duplicate ID input_5_2.
' Duplicate ID input_5_2_3_container.

They all look unique. No?

Thanks,
Jm
