What Jellyfish rule am I breaking?

Puzzler

I was wondering if someone could review this jellyfish grid and tell me what rule I'm breaking.

The situation is that I've found a Jellyfish for 1's in the grid (marked in Green) and identified the candidates to be removed (highlighted in red)

The trouble is the candidate marked in the purple group shouldn't be marked for elimination as it's actually the value for this cell.

I've racked my brains but i cant see what "rule" I'm breaking for Jellyfish, or is it that this technique is only suited to grids where more candidates have been removed?

Thanks again!

The text version is really hard to decipher. Is there anyway to post an image on a message? A screen print would be much easier to read.

I don't see any jellyfish here. Did you overlook the 1 at r7c6?

It is easier to see if you align the candidates and put the grid between code tags:

You forgot to mark [r7c6] Green in column 6. This would force you to add another row ... and that's the rule you would be violating. {Repeating what Pete said earlier, but with a marked PM}

Yep, it was that little critter in [r7,c6]

I'll change my code to look for no more than four cells in a column or row, (depending on the search direction).

Thanks for your help.
