Hello there…

I have two checkbox arrays in a form.

Array 1

[code]
<input class=blank type=checkbox name=gjelderfor[1] value=1>Eget lag<br>
<input class=blank type=checkbox name=gjelderfor[2] value=2>Andre NF lag<br>
<input class=blank type=checkbox name=gjelderfor[3] value=3>Andre frivillige organisasjoner<br>
<input class=blank type=checkbox name=gjelderfor[4] value=4>Ambulansetjenesten<br>
<input class=blank type=checkbox name=gjelderfor[5] value=5>Samband<br>
<input class=blank type=checkbox name=gjelderfor[6] value=6>AMK sentralen<br>
<input class=blank type=checkbox name=gjelderfor[7] value=7>Annet<br>
[/code]

Array 2

[code]
<input class=blank type=checkbox name=problem[1] value=1>Mangel på planlegging/utførelse av oppdraget<br>
<input class=blank type=checkbox name=problem[2] value=2>Feil i disponering av ressurser<br>
<input class=blank type=checkbox name=problem[3] value=3>Svikt i forståelse for situasjonen<br>
<input class=blank type=checkbox name=problem[4] value=4>Materiellmangel<br>
<input class=blank type=checkbox name=problem[5] value=5>Teknisk svikt<br>
<input class=blank type=checkbox name=problem[6] value=6>Mangel på prosedyrer<br>
<input class=blank type=checkbox name=problem[7] value=7>Prosedyresvikt i forhold til eksisterende prosedyrer<br>
<input class=blank type=checkbox name=problem[8] value=8>Annet<br>
[/code]

In each array, when i validate the form, i need to check if at least on checkbox in each array has been checked.
