Key frame and xml issue disapear problem!

I am having a nightmare with this, in that it is effecting me from animating elements using key frames.

For instance I set my xml up fine.

example of some values:-



_root.mc_xml.company.text = _root.mc_xml.company[0];
_root.mc_xml.involvement.text = _root.mc_xml.involvement[0];


No shakes, the first node is being displayed great, but having this in a movie clip if I create a second key frame along a timed period, when the mc hits the keyframe the xml node disapears even without an effect.

I dont know why this happens but I could sure do with a work around because it is driving me mad.

Thanks
