Worksheet Formula Not Working

Can anyone give a non-developer a hand on why this Worksheet formula is not functioning?
The first 3 lines work on their own; however, when I put them together, it doesn’t color the bars. The 4th line I can’t get to work at all. I’m looking to paint the bars on a bullish upswing as follows:

macd(12,26,9).macd > 0 &&
macd(12,26,9).signal > 0 &&
macd(12,26,9).difference > 0 &&
macd(12,26,9).macd > macd(12,26,9).signal

Thoughts? And thank you!!
