Excel 2007 : Test one cell to determine value of another

At work I am trying to update a sheet so that if one cell contains a specific string, in this case its the product name, if the string matches then the price column will automatically be set to the price for that product. I was trying something like =IF(A1='delrin', D1=3.25), but it doesnt seem to work, no matter how i format the string. Maybe a double equal sign is needed to test for equality like in C, or there is a different operator for testing string equality like 'eq' in perl. as you can probably tell, i am not very fluent in Windows, Unix is more my style, so i could really use some assistance. Thank you in advance for any help

=IF(A1="delrin", D1=3.25,"")

Just use double quotes around the string.
Which error do you get?

Thanks for getting back so quick. I'm not sure why that wasn't working for me at work, cause it is working on my home computer. I guess this is my follow up question: If the specified string does not match, is there any way to make it so that it doesnt affect the value in the price column? so if i am searching for "delrin" but the string is "80G33", i want the cell to be left blank so I can fill it in myself. Can i just leave off the third argument to IF? Because when i try that now, it shows up with the value "False". if i put in a blank, will i be able to overwrite that?

As your formula resides i n our cell, if you overwrite the cell's result, the fromula will be overwritten.
You need to use VBA for that
