Token then expected error

[cel]

I am experiencing a token then expected error for the following code with the first AND underlined in red:

if [rev] <1 then "Stopped"
else if [rev] >= 1 AND [rev] <= 100000 then "Below $100K"
else if [rev] > 100000 AND [rev] <= 500000 then "Between $100K and $500K"
else if [rev] > 500000 AND [rev] <= 1000000 then "Between $500K and $1M"
else if [rev] > 1000000 AND [rev] <= 5000000 then "Between $1M and $5M"
else "More than $5M"

how can i get rid of this error?

Hi @cel ,

Try writing all the "AND"s in lowercase as "and".

M language is entirely case-sensitive, so this is probably the issue.
