Does anyone know how I can position I-frames?

I put in this code, but it didn't work!

<br><iframe src="main.htm" name="main" scrolling="auto" width="550" height="276" frameborder=1 style="position:absolute; top: 100; left: 250;">
</iframe><br>

Any ideas on how I can solve this?

try putting in the px measurement...

<br><iframe src="main.htm" name="main" scrolling="auto" width="550" height="276" frameborder="1" style="position: absolute; left: 250px; top: 11px;">
</iframe><br>

That works now, thanks alot!!! *hug* it's obscure how SENSITIVE these codes can be at times... (or so I think. heh)
