Help me with Imacro script

Hello
I want to create imacro so i can automate one process i have..
I want to record script to go to my page in browser and there it has 3 options..i need it to input first like: http://www.website.com/1
then on second it should write Admin
And on third it should click button submit and wait 40sec..then it should open again that tab from beginning and again it should write http://www.website.com/2 (you see now the number is changing) and everything else stays the same..i'm wondering how to automate that so he knows to change numbers?
I know to record the first part..i open new tab that i want, i paste the website i want(for example) http://www.website.com/1 then on second field i write admin and on third i press submit...but when i want to repeat this, it wont go to the same tab but it freezes and stays on that submit button...

Here is code:
VERSION BUILD=8920312 RECORDER=FX
TAB T=1
URL GOTO=about:newtab
URL GOTO=http://www.mywebsite/siteadmin/videos.php?m=membed
TAG POS=1 TYPE=INPUT:TEXT FORM=NAME:embedVideo ATTR=NAME:url CONTENT=http://www.website.com/category/2//rating/?page=1037
