Hi All,
I'll try this differently(I hope). With the below code, variables are
named/set twice ($db, $num, $result, $myrow) etc. In ASP, from what I
remember, that would be a no no. Currently, this code only populates the
1st select box. Coupla Qs. Do I have to connect to the db again, in the
second block of code..? Should the variables in the 2nd block of code,
be named differently to the 1st block.? In ASP the query variables would
be named uniquely, identifying to each query like so, prod_query_num,
prod_query_result and so forth. I must admit, my recollection of ASP is
very vague. Anyway, I hope this explains what I'm looking to understand.
Cheers.
Mark Sargent.
