Just can't figure out what is wrong with this code...snippit

deno

I keep getting an error message on the following code, and I am sure it is something simple that I am overlooking...

··· SELECT gallons_of_water
····· CASE > 7 AND· <= 49
······· average_error_of_sensor = 17
····· CASE > 49 AND· <= 109
······· average_error_of_sensor = 31
····· CASE > 109 AND· <=186
······· average_error_of_sensor = 21
····· CASE > 186 AND <= 255
······· average_error_of_sensor = 11
··· ENDSELECT

Thanks to all...Deno

there he fixed it or you could do

case > 7 and CASE <= 49

you have to supply another variable because the AND thinks your comparing more then one variable at a time.

After reading this thread, I have a question.

The help section in the STAMP IDE V2.1 shows AND as an acceptable Conditional Logic Operator. Why can't it be used? Is the table in the IDE help in error?

willthiswork89

and i suppose would be considered a logic operator because in order for the If to be true both conditions must be true. so it is considered a logical operator because it helps with distinguishing things that need two variables true or the entire statement if false and wont be executed. correct me if im wrong!

Use the "TO" operator for ranges. Also, once you get to the second CASE, you don't need to test for conditions that were true in an earlier CASE. This will work:

SELECT gallons_of_water
    CASE 8 TO 49
        average_error_of_sensor = 17
    CASE <= 109
        average_error_of_sensor = 31
    CASE <=186
        average_error_of_sensor = 21
    CASE <= 255
        average_error_of_sensor = 11
ENDSELECT
