There seems to be a problem running if statements inside an until loop. I think its taking the }. at the end of the if statement as the end of the until loop. Edit. Sorry my bad missed a full stop out. Its all working as it should

I have just found my new number one mod I do have one question, is there a way to set up program loops and if not do you plan to add that in the future?

Just wanted to say thank you for taking the time to make these tutorials. I have finally made my first fuel tank, thanks to you I was over the mun when it all worked.
