Question

I have an error in my button click, and I can’t figure out how to resolve it.

This is my code:

if (ovElements.item(i).name = 'add') and    
(ovElements.item(i).type = 'button') and    
(ovElements.item(i).Value = ' + ') then    
ovElements.item(i).Click;

This is the markup:

<td width="20" align="left"><input class="button" style="width: 30px;" 
 name="add" value=" + " onclick="addLvl();" type="button"></td>

And it gives this error:

Invalid Variant Operation Error

What did I do wrong?

Answer 1

Just a guess:

ovElements.item(i).Value is probably a Variant. If a variant contains a null value you will get that error when you compare it to a string.

Make sure ovElements.item(i) doesn’t contain a null value before comparing it.
