I have no clue help

Question

I am new to spry and I am trying to use it to do a simple
task. I want to have 2 lists one being Make (ie make of the car}
and the other Model (ie model of the car). And you select the make
and it lists the models for that make and once you select the make
and the model it plays a video about that Model of car. I have the
data set done and that was no problem. But I can figure out how to
do the rest. If some one could point me in the right direction I
would be so greatful. thank you
<div spry:region="ds1 ds2" class="MasterContainer">
<div class="DetailColumn" spry:="ds1" spry:setrow="ds1"
spry:hover="MasterColumnHover"
spry:select="MasterColumnSelected">
</p>
<form name="form1" method="post" action="">
<span id="spryselect1">
<label for="Make">Make</label>
<select name="Make" id={make} title="{make}">
<option value="{make}">{make}</option>
</select>
<span class="selectRequiredMsg">Please select an
item.</span></span>
<p> </p>
</form>
<form name="form2" method="post" action="">
<span id="spryselect2">
<label for="Model">Model</label>
<select name="Model" id="Model" title="{ds2::model}">
<option value="{model}">{model}</option>
</select>
<span class="selectRequiredMsg">Please select an
item.</span></span>
</form>
