Root cannot seem to make second partition on sd card?

[paddroid]

Hello

i have a galaxy s3 mini 18190N with a 32gb external micro sd card and basically the phone started lagging and space was low so i looked at rooting with the purpose of using apps like app2sd and link2sd to move apps to the 32gb card.

i have since managed to root the device but cannot seem to use link2sd properly as it is not recognizing a second partition? i seem to have become lost in all the apps ive downloaded to try and create this elusive 2nd partition on my sd card.

please can you help a noob out and get my phone running swiftly again

thanks
