Hi,

I have a problem with using replaceselection in a function. Everything works fine ( I have checked by substituting the lettervariable and letter[loop]) until I want to update a particular text object using the "lettervariable" as seen below.

I have used something similar before but, as is always the case, I can't now find it!
============================================

function CheckLetter(LetterPressed)
{
for (Loop = 1;Loop < letter.length +1;Loop ++)
{
if (LetterPressed == letter[Loop])
{
var lettervariable = "letter" + Loop
eval(lettervariable)

CheckLetter1 = lettervariable // checks variable works

lettervariable.SetSelection(0,-1)
lettervariable.ReplaceSelection(letter[Loop])

}
}
}

============================================

The function should iterate through to check to see if a particular letter (letterpressed) is found within the characters in a word (previously read into an array).

There is probably something obvious that too much Christmas spirit has made me overlook, so any help would be appreciated.

Regards

I guessing here, but has Loop been declared? In the For loop, if Loop has not been declared then ReplaceSelection(letter[Loop]) will not have anything to replace. If this is the problem then try:

for (var Loop = 1;Loop < letter.length +1;Loop ++)
etc.

Hope this helps.

Paul,

Thanks for your reply

I worked it out for myself in the end as the help file was a little ambiguous!

I had put:

lettervariable.SetSelection(0,-1)
lettervariable.ReplaceSelection(letter[Loop])

not realising that a more specific use of "" was needed with the eval statement.

It finally looked something lik:

eval("letter"+offset+ ".SetSelection(0,-1)")
eval("letter"+offset+ ".ReplaceSelection(letter[Loop])")

By the way, the loop does not have to be declared in the IF statement - I had been through all those possibilities too!

Thanks for you interest.
