【求助】 关于用户界面 怎么让用户输入的东西作为变量接着运行？

还有在创建用户界面的时候后面的代码为什么会先于前面的代码运行？

InputString[请问您的目标是什么]
ChoiceDialog[请问您有几个准则, {1 -> 1, 2 -> 2, 3 -> 3, 4 -> 4, 5 -> 5,
6 -> 6, 7 -> 7, 8 -> 8, 9 -> 9}]
CreateDialog[
{TextCell["第1个准则"], InputField[Dynamic[准1], String],
TextCell["第2个准则"], InputField[Dynamic[准2], String],
TextCell["第3个准则"], InputField[Dynamic[准3], String],
TextCell["第4个准则"], InputField[Dynamic[准4], String],
TextCell["第5个准则"], InputField[Dynamic[准5], String],
TextCell["第6个准则"], InputField[Dynamic[准6], String],
TextCell["第7个准则"], InputField[Dynamic[准7], String],
TextCell["第8个准则"], InputField[Dynamic[准8], String],
TextCell["第9个准则"], InputField[Dynamic[准9], String],
DefaultButton
[DialogReturn[ret = 准1]
DialogReturn[ret = 准2]
DialogReturn[ret = 准3]
DialogReturn[ret = 准4]
DialogReturn[ret = 准5]
DialogReturn[ret = 准6]
DialogReturn[ret = 准7]
DialogReturn[ret = 准8]
DialogReturn[ret = 准9]
]
}];
CreateDialog[

TextCell["第2个方案"], InputField[Dynamic[方2], String],
TextCell["第3个方案"], InputField[Dynamic[方3], String],
TextCell["第4个方案"], InputField[Dynamic[方4], String],
TextCell["第5个方案"], InputField[Dynamic[方5], String],

TextCell["第7个方案"], InputField[Dynamic[方7], String],
TextCell["第8个方案"], InputField[Dynamic[方8], String],
