First Child product not selected automatically

[jgbauer]

hi everyone anyone know how to fix this? i have 3 child products. but when i visitor views the product details of the parent product it does not select the first child product. it just shows a please select variable button. unfortunately the way the drop downs work with child products there is in fact one selected.
