Oracle "SQL Error: Missing IN or OUT parameter at index:: 1"

Question

I have an Oracle script that looks like the following:

variable L_kSite number;
variable L_kPage number;
exec SomeStoredProcedureThatReturnsASite( :L_kSite );
exec SomeStoredProcedureThatAddsAPageToTheSite( :L_kSite, :L_kPage );
update SiteToPageLinkingTable 
set HomePage = 1 
where kSite = :L_kSite and kPage = :L_kPage;

Supposedly the last statement is a valid use of a bind variable but when I try to run the script I get this on the last line:

SQL Error: Missing IN or OUT parameter at index:: 1

I'm not sure how to proceed here as I'm not especially proficient in Oracle.

Answer 1

Based on the comments left above I ran this under sqlplus instead of SQL Developer and the UPDATE statement ran perfectly, leaving me to believe this is an issue in SQL Developer particularly as there was no ORA error number being returned. Thank you for leading me in the right direction.
