Alright So....I'm trying to replace the array values when I hit my 'add' button, and then when i hit the summary button it displays the initial array values, the ones i preloaded in, and the new, updated ones. Any help here is much appreciated, been workin on it for days
Questions being:
1. How do I achieve the proper effects with my add and summary buttons, right now it will display the initial values but not the ones I add in using my add button.
2. How do I make it so that when it appends null to my textArea to actually make it append "N/A" instead, current method isnt working properly

private String brandXString;
public void setValues(String plainWrap, String brandA, String brandB,

if (plainWrap != null) {
plainWrapString = plainWrap;
} else {
plainWrapString = "N/A";
}
if (brandA != null) {
brandAString = brandA;
}
else {
brandAString = "N/A";
}
if (brandB != null) {
brandBString = brandB;
} else {
brandBString = "N/A";
}
if (brandX != null) {
brandXString = brandX;
