Yep otherwise it will iterate through the entire block line by line & if you change the value in previous block then it might end up triggering value of next block if value is same as whatever you just changed it to.

P.S: you need to close off the if queries with end if action parts. There should be the same amount of end if as there are if. Where you put the end if action parts depends on the query. In this case you need to add them all to the end of the query.

Ahh, ok. Thank you very much!
