Hi all.

I have this:

Expand|Select|Wrap|Line Numbers
  1. <input type="text" name="agg" size="30" value="---" readonly>
  2.  
  3. <select size="1" name="provv" onchange="var cc = this.options[this.selectedIndex].value; if(cc=='GAM')Popup(400,200,'GAM.asp');">
  4. <option value="">---------</option>
  5. <option value="GAM">GAM</option>
  6. <option value="GBM">GBM</option>
  7. </select>
If select GAM value open popup... I need if select GAM the value of field input type text "agg" is value null, deleted default value "---"... it's possible ?

Can you help me?

sure, though it’d be easier, if you gave the field an id.
