Trying to create a Dynamic array from a somewhat complex formula but keep getting #N/A errors randomly.
For some reason, the y value of the equations doesn't like it.
Effectively the #N/A for the first instance is saying it can't find 0.57 in the particle diameter table on the left, despite clearly being listed.
Data to mimic:
Table1:
| Particle Diameter δ (μm) | Rairborne(δ) (kg/s) | γ(δ) |
|---|---|---|
| 0.00 | 0 | 0.000555556 |

InputParameters:

Problematic Formula:
=MAKEARRAY(10,11,LAMBDA(x,y,IF(x*7.8 <= InputParameters[[Spray Duration (minutes)]:[Spray Duration (minutes)]] * 60,XLOOKUP(y*0.19, Table1[[Particle Diameter δ (μm)]:[Particle Diameter δ (μm)]], Table1[[Rairborne(δ) (kg/s)]:[Rairborne(δ) (kg/s)]]) * (1 - EXP(-XLOOKUP(y*0.19, Table1[[Particle Diameter δ (μm)]:[Particle Diameter δ (μm)]], Table1[[γ(δ)]:[γ(δ)]]) * x*7.8)) / XLOOKUP(y*0.19, Table1[[Particle Diameter δ (μm)]:[Particle Diameter δ (μm)]], Table1[[γ(δ)]:[γ(δ)]]),XLOOKUP(y*0.19, Table1[[Particle Diameter δ (μm)]:[Particle Diameter δ (μm)]], Table1[[Rairborne(δ) (kg/s)]:[Rairborne(δ) (kg/s)]]) / XLOOKUP(y*0.19, Table1[[Particle Diameter δ (μm)]:[Particle Diameter δ (μm)]], Table1[[γ(δ)]:[γ(δ)]]) * (1 - EXP(-XLOOKUP(y*0.19, Table1[[Particle Diameter δ (μm)]:[Particle Diameter δ (μm)]], Table1[[γ(δ)]:[γ(δ)]]) * (InputParameters[[Spray Duration (minutes)]:[Spray Duration (minutes)]] * 60))) * EXP(-XLOOKUP(y*0.19, Table1[[Particle Diameter δ (μm)]:[Particle Diameter δ (μm)]], Table1[[γ(δ)]:[γ(δ)]]) * (x*7.8 - (InputParameters[[Spray Duration (minutes)]:[Spray Duration (minutes)]] * 60))))))Correct data (When using the long formula and dragging) (particle size on top, Time down the LHS):
