If statement not working inside for loop for file saving?

[Whatevermajorloser]

Hello!

I have the following documents open in Photoshop:

123456_mrp_ou.tif

869548_mrp_ou.tif

896589_mrp_in.tif

896589_mrp_ou.tif

..and I have this if statement within a for loop to look for files with a specific "pid" number and save them in my Documents folder:

var originalPid = 896589
for(i = 0; i < app.documents.length ; i ++) {
      activeDocument = app.documents
        if(activeDocument.name.substring(0,6) === originalPid) {
                var standardSave = new File('/Users/constantincerdan/Documents/' + activeDocument.name)
                activeDocument.saveAs(standardSave, TiffSaveOptions, false, Extension.LOWERCASE)
}
}

This does not find the two files and save them when I run it. However, the for loop without the if statement runs just fine and saves all the documents into the Documents folder:

var originalPid = 896589
for(i = 0; i < app.documents.length ; i ++) {
      activeDocument = app.documents
                var standardSave = new File('/Users/constantincerdan/Documents/' + activeDocument.name)
                activeDocument.saveAs(standardSave, TiffSaveOptions, false, Extension.LOWERCASE)
}

How do I get it to work with an if statement so that it only saves those two?

Any help is much appreciated!

You are comparing apples with oranges, you need to compare strings.

originalPid = 896589;

alert(typeof originalPid);

Doh! How silly of me. I should have noticed this myself. Thank you, Philip.
