Oh, sorry, what I meant to say was that you should find the line of code like this:
<input type="text" size="4" value="1" name="PracticeCart_1_Quantity_Add" />
And add in the style so it looks like this:
<input type="text" size="4" value="1" name="PracticeCart_1_Quantity_Add" style="vertical-align: top;"/>
The style="vertical-align: top;" is adding the vertical align to the element.
