Hide/Unhide Entire Row With Button IF

Hello,

Been looking all over for this but still need help. I could not find the answer in other posts.

I'm trying to get a Button to hide and unhide rows depending on Column A only which is a pasted link to other sheets. The rows should hide when Cell A is empty or 0.

or 2 buttons one for hiding and the other for unhiding rows

Can someone help me out plz.

Thx.
