Seems to be working now.
Good first try! As someone that has been using Poser for quite a long time, I can tell you that it's not easy.
If I may make a suggestion that should make your life easier, though? On those parameter dials, you should have a right-pointing triangle for each of them. For the ones being animated, click on the triangle and pick "Graph". This will open the graph editor for that parameter, featuring a line that curves over time (frames from left to right, parameter amount from top to bottom). You can force the line to act in a certain way for certain body parts' parameters by clicking the keyframe (denoted by a black tickmark on the red line) then on one of the four buttons on the bottom left of the graph editor.
The left one is "spline" which allows a smooth transition from one keyframe to another, starting slowly, moving quicker, then slowing down as it approaches the key frame.
The second is "linear" which allows for a straight mathematical transition from one keyframe to the next.
The third is "constant" which allows you to hold the parameter all the way from one keyframe to the next. If there's a difference, it'll snap the parameter from one position to the next over exactly one frame, causing a pop in the animation.
The fourth is "break spline". This will separate the spline on the left from the spline on the right to create a hard transition. This is useful if you have something hitting a hard object such as the ground and you want, say a foot, to spline its way to the ground then hit the ground without passing through it or slowing down to smoothly settle on the ground.
The graph editor in Poser needs a serious upgrade. One of my main gripes with the program. In other 3D software, you can fine tune the graph editor much more using handles like the Pen tool in Photoshop. I wish that'd be a feature they would implement.
Good luck on your animating adventures!
