Every time I start mining it picks a random coin?

So I'm trying to mine with CGminer 3.7.2, but every time I launch the .bat script to start mining, it appears to pick a random coin to mine based on the algorithm (Scrypt or SHA-256) that I chose. I don't know how I'm supposed to specify which coin I want to mine. I want to mine Dogecoin and Litecoin. How can I specify that I want to mine only Dogecoin and Litecoin? TiA

That's the whole point of prohashing, it picks the most profitable coin and then you can just get paid out in the coins you prefer. You end up making more in the end. I used to just mine for digibyte then switched to the prohashing system and it's worked out well.

What do you mean by that?
And I don't want to mine "the most profitable coin" I want to mine the coin I want to mine and nothing else.

With prohashing, you mine what they want to mine and they pay you out in what you want.
If you want to mine a specific coin, you want to find a pool that mines that or solo mine.

This isn't "mining" this is "leasing your miner to prohashing and choosing your payment form".
