Return Worksheet Name To Cell

I am looking for a way to refererence the text of another cell, not the formula that it contains.

I have a workbok that has 5 worksheets. On the first worksheet, a certain cell (lets say A1 for simplicty) uses the function: UPPER(MID(CELL("filename"),( FIND("]",CELL("filename"))+1),50))
to retrieve the title of the worksheet. (ie, A1 now serves as a title cell, matching the name of the worksheet).

My problem is, on the following four worksheets, I also want A1 to reflect the contents of the first worksheet's A1. I've tried using =Worksheet!A1, and =CELL("contents", Worksheet1!A1), and so forth, but my problem is, it reflects the formula of A1, not the returned value of the formula (the title). Initially, it works, but if I recalculate the cells on the four worksheets, it changes them all to the title of the current worksheet, not the first worksheet.

Is there a formula that I can use to retrieve the TEXT and not the formula?
