adding text on catelog page in woocommerce

Hello,

First of all, i am dutch, so my English isn’t perfect, i hope i can explain it correctly.

We have build our website with woocommerce because with every product i add to my shop it makes an single product page. Of course is the text on the single product page easy, i can describe my product and put in al product information. I have 4 categories, Promotion, Easter, Sint and Christmass chocolate. For example, i have my easter chocolate page with all my easter products, on this “shopping page” i want to add text above the products and on the bottom of the page, below te products. I want to add text here with the options my customers have with the chocolate and i want to promote the categorie with the text. In the text on the bottom i want to put my information for contact and i want to put as many related words in the text to be found on more words in google.

Now i have tried for days to look for a solution, but i haven’t found one yet. I have found a code to put in my functions.php but everytime i put in this code and click on save i get a white screen, then i have to go to my FTP (filezilla) and remove the code there and save it and then the white screen is gone and i can see the website again. I don’t know if to code is bad or if i am doing something wrong but i need it to work.

Can somebody help me.. maybe there is a plugin for this or there is a code that will work, i just hope someone can help me cause i really want to have text on the pages.

Thanks! Greets Jaimie
