Form reset on change

[petenaylor]

Hi all

 

I have a filter system on a website I am creating and there are three forms each sends a value to the url using get.

 

Every time a user selects the drop down on the first form it send to the url and then a SQL query is run to select items from a database which works great for all three forms.

 

However, the problem I have is when the user goes and re-selects a category from the first form it needs to reset the other two below it and emptying the url parameter for both so it just asks the SQL to select the items from that category again.

 

Please help

 

Many thanks

Pete
