Struggling with AWK

I know this is an easy problem, but I've been struggling with it all morning and finally admit I need help.

I have two files that I need to compare. After doing this the easy way (grep -F) I realize that there are other fields in file2 that match field1 in file1, so I turned to awk.

I want to compare the first field in each, and if field1 of file1 matches field1 of file2, print out the entire line in file2. I've been trying to write an awk script but just don't fully understand how to do this.

I get as far as:

Code:

awk '
FS="\t";
BEGIN {
while (getline <"file1.txt"){
$fieldq==$1;

and I can't figure out how to read in the second file to do the comparison and then print $0 from file2.
