"The quantity must be a valid number greater than 0" error message

I changed variations in a listing and then tried to revise the listing and I get this error, see attached image00%20am

If I duplicate the listing and try and list a new listing all together rather than revise I get the same problem. I believe its to do with variations, its like ebay thinks it is a non variation listing looking for a quantity but because of the variation quantities are varied.

Now if I create a whole new listing then copy over text, images and recreate the variations this will work in creating a new listing, I have had to do this before but I don’t want to have to do this, it adds so much time when it should be just straight forward.

Any help? thanks

All good, I fixed the issue, one variation was in the negative that fixed the issue
