Perhaps you should finally show us your code. We're bad at guessing.

a different Number is being passed as Boolean for some reason, but makes no sense as obviously numbers are not Boolean and I do not know where it is being called from

The odd thing is sometimes this error fires and sometimes it does not. Does it have to do with activities closing and starting? I am seriously confused. Should also note that when it does fire it closes out application. Also there is no line 0 with code

Those two lines indicate the error occurring in PracticeAdd1 activity. Check it carefully.

Do While Answer3 = 2 Or Answer2
Click to expand...
Shouldn't it be:
Do While ((Answer3 = 2) Or (Answer3 =Answer2))
?
Similarly in Answer4 code loop.

Another way to write code with similar goal could be to keep track of already randomly selected numbers and discard repetitions. Think about an array of 10 bytes; when you randomly select a candidate you first check it against the array and if not used than assign it to next Answer variable and mark it accordingly in the array.
As an additional measure, having AnswerX vars defined as an array will let you do all the "init" in a for-next loop.
