#### BASAL Problem

Hey, all
Anybody here familiar with BASAL language?
It's said to be an "XML based programming language which is translated into other programming languages before being compiled Derives its syntax from C style languages such as Java C Flex iPhone BlackBerry Windows Mobile Palm OS Symbian Linux J2ME Android".
I'm STRUGGLING to write a program to calculate the least common multiple for two numbers in BASAL language. And the program should only consider the first twenty multiples of each number. Once the counters both exceed 20, it will show "no answer".
I know basically, a outer while loop and an inner one are needed, but I just can't make them right!
Here's what I have now. The LCM I got for 3 and 7 is 42!

GET number1
GET number2
ASSIGN counter1 = (1)
ASSIGN counter2 = (1)
ASSIGN m1 = (number1)
ASSIGN m2 = (number2)
WHILE m1 != (m2)
BEGIN
ASSIGN m1 = (m1 * counter1)
IF counter1 < (20)
BEGIN
WHILE m2 != (m1)
BEGIN
ASSIGN m2 = (m2 * counter2)
ASSIGN counter2 = (counter2 + 1)
IF counter2 >= (20)
BEGIN
ASSIGN m2 = (m1)
ASSIGN answer = (-(1))
END
IF counter2 < (20)
BEGIN
ASSIGN answer = (m1)
END
END
IF answer != (-(1))
BEGIN
SHOW "FOUND"
END
IF answer == (-(1))
BEGIN
ASSIGN m1 = (number1)
ASSIGN m2 = (number2)
ASSIGN counter1 = (counter1 + 1)
ASSIGN counter2 = (1)
END
END
IF counter1 >= (20)
BEGIN
ASSIGN m1 = (m2)
ASSIGN answer = (-(1))
