How to fix this error?

A table is denoted by the keyword TABLE, the language-independent table
name and a list of arguments. Each argument consists of <formal
parameter = arg>, for example:
TABLE TEST_TAB(COLOR='red', PRICE=PRICE_1)
Here, COLOR and PRICE are formal parameters of the table, 'red' is a
constant, and PRICE_1 is a characteristic-specific variable.
A function is denoted by the keyword FUNCTION. The other entries for a
function are the same as for a table, for example:
FUNCTION TEST_FUN(COLOR='red', PRICE=PRICE_1)
One argument is invalid. Arguments must be either constants or
variables which refer to a characteristic. Check the arguments and
correct the error.
