Show Hide Table row depending on a variable

[richard-elland]

Hi
I have a multipage form. I can put data entered in hidden form elements from previous pages. I want to show or hide table rows depending on this data value.
For example, I collect a list of names in first form, but if some names are blank I dont want to show the table row associated with that name to collect more data.
I have seen loads of code to toggle rows but cant find any which shows me how to toggle on a variable.
Thanks in advance.

Can you show us the actual code? Then, maybe we can help.

I haven't written any code - that's what I'm asking for.
Below are 2 table rows.
I want to show the second row if $adult2fn is not empty.
I can set $adult2fn as an hidden value elsewhere in the form.
Thus

<input type="hidden" name="adult2fn" value="$adult2fn" />

        
<tr>
        <td width="189">$name $adult1sn</td>
        <td colspan="2">I agree to the membership conditions of DCN Ltd</td>       
        <td width="56"><input id="tick1id" name="tick1" type="checkbox" checked="checked" /></td>
    </tr>
<tr>
        <td>$adult2fn $adult2sn</td>
        <td colspan="2">I agree to the membership conditions of DCN Ltd</td>       
        <td><input id="tick2id"  name="tick2" type="checkbox" checked="checked" ></td>
    </tr>
