How do I make first entry not valid Choose week; choose week week1;week1 week2;week2 week3;week3 And what is the best way to make dependency between dropdown menues? First dropdown is populated from SQL query.... need to use selected from this menu to populate next dropdown from another table.

RE:Validation Regular expression

Hello.

As you already suggested in your headline, you can write regular expression for that. Optional, you can write “value;name” as “1;choose name” and validate selected value for number (using Regex).

As for your second question, please refer to following KB article:
