local lava = peripheral.wrap("iron_tank_valve_2")

local lavatank = lava.getTanks("unknown")
if not lavatank[1].amount then
  lavatext = "Lava: Empty"
   else

Split into new topic.

You should be able to put a while true do on the line after the peripheral.wrap line and an end at the end, and it should work fine.

i did that but it still dosent work it dosent update when more liquid is added or liquid is taken out of the tank no matter how long i wait is there any other way?

Thanks for the help alot i had the while true do part placed in the wrong area its fixed now THANK you so much
