DAX Formula Question

[PrivateAnalytic]

Hello all! I am reaching out because I created a table which displays scores from a current month and previous month, and the % change from them. (See Below). One question I was wondering is if there was a way to include in my DAX formula which show if a previous month score or current month score is not showing anything, then there is no % change? I highlighted the examples.

@PrivateAnalytic , try a measure like

if(isblank([current month]) || isblank([previous month]) , blank(), divide([current month], [previous month]) )
