I am having the same problem as THUNBUG. I followed the steps in the text file "install_value-mod_137.txt" to "Configure the Shop" exactly (tried it three times). However when I try to add the Attribute to the product, "Attribute Option and Option Value Do NOT Match - Attribute was not added - : TEXT". is displayed in red on top of the screen.

This is exactly what I have done:

Went to Catalog->Option Name Manager
Entered the text "Value" in the Option Name field.
Selected "Value" in the drop down list under option type
Went to Catalog->Attributes Controller
Selected Categories: - Gift Certificates (created previously)
Selected the Gift Certificate product
In the "Adding New Attributes" section, I clicked "insert".
Option Name was "Value [Value]" and Option Value was "TEXT [RESERVED FOR TEXT/FILES ONLY ATTRIBUTES] are pre-populated, can't edit those field (or at least I don't know how). Didn't change anything else.

Also followed your advice:

Could you please try and remove the entry in Admin->Options Name Manager. You can also try and remove the product itself too and create a new. Then add the option name again in the Option Name Manager and then go to Attributes Controller and choose your product and select "Value" from the Option Name and don't select anything in the Option Value-field. Click Insert. Still the same error?

There isn't a way to "not select anything in the Option Value-field", it has TEXT [RESERVED FOR TEXT/FILES ONLY ATTRIBUTES] in it and you can't remove it.

I have configured the option name and tried to use it for Attributes Controller, but perhaps I am missing a step (not included in the instructions) for option value?

Please advise, I would love to use this mod but I cannot get it to work.
