JAVASCRIPT - - HELP NEEDED please

javascript help needed..PLEASE HELP

hello there i am new to this forum, and i hope someone will help me

now let me explain what i need

i have to modify a hangman game to add different levels (example level1, level2, and level3 as rtadio buttons) and a drop down list allowing the player to choose different topics..but i aint got a clue how to do it

each time a player chooses a topic from the drop down list, that topic has different sets of words, for example, if i chose a topic as countries, it would contain a list of countries, and if i chose the topic vegetable it would contain a list of different veggies, then once someone has chosen a topic they can choose the level they wish to play at, level one being easy and level 2 being hard

so can someone please help mme out here

a good site for help would be experts-exchange.com for this type of script

thanks..if any one has any suggestions please do help
