Hi!

I am investigating the effect of balanced ambidexterity and combined ambidexterity on firm performance, with moderating variables environmental dynamism and environmental munificence.
While my main relation is insignificant, the interaction effect of my moderating variable is significiant.
How do I need to interpret this, and can I give support to the proposed hypothesis of a positive moderating effect if the main effect is insiginificant?

Note: for the moderating variables, variable * BD or variable * CD stands for interaction term with m
