I think you just got the formula the wrong way around, that is all.

Price elasticity of demand is: percentage change in quantity demanded divided by percentage change in price.

The percentage change in quantity demanded is +20%.
The percentage change in price is -30%

PED is +20 divided by -30, so -0.67.
