iMacros - Loop - Help with Javascript

Can someone help me with this. I have csv file which will have 3 columns ideally.
Column 1 - Website link to load, Column 2 - number of times consequent page scroll or Next button to be clicked for that particular page alone and Column 3 is going to number of Products for which Hyperlinks needs to be extracted.

Now the problem I have is to build a script to Run 3 steps sequentially and Step 2 and Step 3 alone will have Loops defined based on the value detailed in CSV columns 2 and 3.

Step 1 - Load the website 1 listed in Col1 of the CSV
Step 2 - Take the custom value for fetch / scrol / next page numbers to be clicked
Step 3 - Once all the next pages and fetches are loaded and ready for extraction. Take the custom value from Col 3 in CSV for the number of products / listings for which links needs to be extracted.

Code below,

var macro = "CODE1:";
macro += "VERSION BUILD=10022823" + "\n";
macro += "SET !EXTRACT_TEST_POPUP NO" + "\n";
macro += "SET !ERRORIGNORE YES" + "\n";
macro += "SET !TIMEOUT_PAGE 1" + "\n";
macro += "SET !REPLAYSPEED FAST" + "\n";
macro += "SET !DATASOURCE C:\\dummy\\Links.csv" + "\n";
macro += "SET !LOOP 1" + "\n";
macro += "SET !DATASOURCE_LINE {{!LOOP}}" + "\n";
macro += "SET !DATASOURCE_COLUMNS 3" + "\n";
macro += "URL GOTO={{!COL1}}" + "\n";
macro += "TAB T=1" + "\n";
macro += "TAB CLOSEALLOTHERS" + "\n";


var macro = "CODE2:";
var m;
macro += "SET !DATASOURCE C:\\dummy\\Links.csv" + "\n";
macro += "SET !LOOP 1" + "\n";
macro += "SET !DATASOURCE_LINE {{!LOOP}}" + "\n";
macro += "SET !DATASOURCE_COLUMNS 3" + "\n";
macro += "URL GOTO=javascript:window.scrollBy(0,20000)" + "\n";
macro += "TAG POS=1 TYPE=DIV ATTR=ID:fetch{{i}}" + "\n";
macro += "TAG POS=1 TYPE=DIV ATTR=ID:scroll{{i}}" + "\n";
macro += "WAIT SECONDS=0.2" + "\n";
macro += "m={{!COL2}}" + "\n";
for(var i=0;i<m;i++)
{
iimSet("m",i)
iimPlay(macro);
}
iimDisplay("ScriptCompleted")
