Error in ampscript syntax - salesforce

Question

Please help me figure out the problem in my ampscript.
So here it is:
%%[ Var #phone Set #phone = Lookup(“Support Phone Numbers”, “Phone”, “Locale”, "%%Opportunity:Account:Locale__c%%") ]%%
The result of the script is placed in email like this:
%%=v(#phone)=%%
But when I try to preview the email I get this error:
There is an error in your email. Please contact your customer service representative.
Error 1: Script SET Statement Invalid

Answer 1

The issue appears to be caused by the 2 different styles of double quotes (") being utilized within the function.
For instance:
Lookup(“Support Phone Numbers”, “Phone”, “Locale”, "%%Opportunity:Account:Locale__c%%")
Should look like:
Lookup("Support Phone Numbers", "Phone", "Locale", "%%Opportunity:Account:Locale__c%%")
Also there is the was a problem with %% wrapping for Opportunity:Account:Locale__c
Finally the script should look like this:
Lookup("Support Phone Numbers","Phone","Locale",[Opportunity:Account:Locale__c])
Thanks.
