Harrison, to expand a bit on Faheem's feedback (thanks!), we have a good overview of the "Write to Table" functions here:

Those columns, like most others, also have a "Run settings" section where you can designate the "Only run if..." conditions.
If you're having trouble with any specific table, share a link there and I'm happy to have a look with you.
