    <p>This little snippet of code for some reason isn't working properly. What this is supposed to do is make a move if <code>i</code> is less than <code>colLength</code>, which is 2 at this point meaning it should stop after typing in 7. And for some reason it keeps going until the end of the array.</p> <p>Why does it keep going? I don't have any bit of code that increments <code>r</code>? </p> <pre><code>//this is a 5 step process, this is the 4th if (stepMaker == 4 &amp;&amp; numLocation &lt; totalSteps){ //looking through the array for the last number used in step 3, this works for (int r = 0; r &lt; gridRow-1; r++){ for (int c = 0; c &lt; gridCol-1; c++){ // still looking //using 5 instead of numLocation works, numLocation keeps going however... why? if(grid[r][c] == (numLocation)) { int x = 1; for(int i = 0; i &lt; colLength; i++){ grid[r + x][c] = numLocation + 1; System.out.println("x=" + x + " // " + "numLocation=" + numLocation + " // " + "r=" + r + " // " + "c=" + c + " // " + "stepMaker=" + stepMaker + " // " + "colLength=" + colLength + " // " + "rowLength=" + rowLength); numLocation++; for (int xx = 0; xx &lt; gridRow; xx++){ for (int yy = 0; yy &lt; gridCol; yy++){ System.out.print(grid[xx][yy] + " "); } System.out.println(""); } x++; } } } } //colLength++; stepMaker++; } </code></pre> <p>And this is the output:</p> <pre><code>x=1 // numLocation=5 // r=2 // c=2 // stepMaker=4 // colLength=2 // rowLength=3 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 5 4 3 0 0 0 0 6 1 2 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 x=2 // numLocation=6 // r=2 // c=2 // stepMaker=4 // colLength=2 // rowLength=3 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 5 4 3 0 0 0 0 6 1 2 0 0 0 0 7 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 x=1 // numLocation=7 // r=4 // c=2 // stepMaker=4 // colLength=2 // rowLength=3 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 5 4 3 0 0 0 0 6 1 2 0 0 0 0 7 0 0 0 0 0 0 8 0 0 0 0 0 0 0 0 0 0 0 x=2 // numLocation=8 // r=4 // c=2 // stepMaker=4 // colLength=2 // rowLength=3 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 5 4 3 0 0 0 0 6 1 2 0 0 0 0 7 0 0 0 0 0 0 8 0 0 0 0 0 0 9 0 0 0 0 rowLength = 3 // colLength = 2 </code></pre>

    2. CONow I feel stupid. Sorry. And why does it only run through it twice then? Step 4 should only be called once, but for some reason this is the only step that goes twice even though the code is almost exactly identical to the other 3...

    3. COI will suggest you to debug your code. I cant tell you why just by looking at this code snippet. But the block where are you printing values should take a closer look.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
