Modify an existing MT4 script

I want to modify 2 existing MT4 scripts one that enters a 'buy market' order and then enters a target and stop loss price.

The second enters a 'sell market order' and then enters a target price and a stop loss price.

 I want both scripts modified to require an input that will enter a 'buy limit order' or a 'sell limit order' then enter the target and stop loss price.

 Or better yet, combine both existing scripts to enter either a 'buy' or 'sell' limit order then after the limit order is executed it then modifies the order for a 'target & stop loss'.  

When I click on the script a pop-up window will appear that will ask "BUY or SELL" then requires a "Limit Price" for that order.
