I'd really appreciate any input as to way the if statements are not working when I have 2 conditions in them but will work when I have 1 condition.
Edit:
I have corrected the typos in the code. My laptop gave up on me last night so I had to retype the code on a friends laptop, hence the typos and why I didn't post the whole code initially.
The IF statements still don't work as stated above when the 2 conditions are in the IF statements together, but when I only put 1 condition in, it works fine.
