Vendors and permissions

I am selling a prefab that I have put in the inventory of a prim and created my own little vendor script. I'm using a fast pay button for the user to pay and then an llGiveInventory in the money event.

I have all 71 prims in the prefab set to next owner can modify and copy but not transfer. The 3 or 4 door swing scripts I have set to next owner can copy, but not modify or transfer.

So I am having two issues. First, when I log in as an alt to test the vendor, I get a script error saying that it (meaning, I assume, either the script or the vendor prim) doesn't have permission to transfer.

So, do I have to give full perms when I put it in the vendor's inventory (because the vendor is becoming the "next owner" and then have the vendor change them to no transfer (for the next next owner)?

Second issue, albeit less critical, is that in my inventory the prefab says (no transfer) (no modify). I am assuming that the whole thing is saying (no modify) because the scripts have no modify? I haven't gotten it transfered to my alt yet to test, but when another user gets the whole thing, will they be able to modify anything? Ideally, I would like them to be able to modify the prims if they want, but I would prefer they not be able to open the scripts. Is that possible or do I just need to open up the scripts if I want them to modify the building?

Oh, btw, I am the creator and owner of every prim and every script.

Your prefab itself isn't transferrable atm.
Most probable cause is a no-transfer item in the contents of one of the prims. Check them for no-transfer scripts or textures.

Your script is probably working fine with transferrable items.

Aha! Thank you...

I found two stray scripts from an old TP setup I was using. They had no perms. Got rid of them and everything worked.

Thanks again.
