I’m generating a slightly different mistake than expected:

There is a mistake in the backward propagation! difference = 2.4577112074727173e-07

**Expected output** :

**There is a mistake in the backward propagation!** difference = 0.2850931567761623

I don’t think my array indexing or variable referencing is incorrect because I worked through those errors to generate the difference

I triple checked my order of operations on both gradapprox[i] and difference calculation lines. What else am I missing?
