Macro Warning message? DEXTROSE?

[ybz12003]

Hello, 

I got a warning message from Macro.   Please advise how to fix it.

495 proc sql noprint;
496 select quote(trim(Mecication_list)) into : Medicationslist separated by ',' from
496! Medications_CIN;
497 quit;

Looks like that character variable has values like %DEXTROSE or %OINT in there.

Use SINGLE quotes to prevent the macro processor from trying resolve those apparent macro calls.

select quote(trim(Mecication_list),"'") ....
