I don't have a goal weight?!?!

Here's a really good tool to figure your ideal weight using height, gender and age: It gives several different options for calculations. Most of the calculations used aren't realistic for me but the healthy BMI recommendation gives a more realistic range.

Everyone is different, and those charts are only statistics. Honestly, I think it's a good thing not to have a goal. Pounds on a scale are only a number, so shoot for a weight which you feel comfortable with. Use a BMI chart only as a general range you want to make it to. Then decide for yourself what weight is right for you.
