Using the Do Until Loop, here’s the code:
x=0
y=1
Do until x>=21
x=x+y
y=x-y
Print x
Loop
this code will print upto the value of 21. Just change the value of 21 with whatever you like. This is written inside a command button. Make sure of indentions in the 2, 3, 4th lines. The result prints in the form.
